The present invention relates to apparatus and methods for single and multiple person vehicle car seats and specialized car seats. More particularly, but not exclusively, it relates to apparatus and methods for a car seat system, a dual person car seat, overlapping car seats, changeable car seats, insertable car seats, an integrated car seat system, variable width car seats and multiple person car seats.
The present invention is concerned with special vehicle seats. Heretofore, each vehicle car seat was a small removable seat generally equipped with a restraining device or harness and can be fastened to the seat of a vehicle for securing a person in the vehicle. Most often it is a seat that is portable for use in the automobile and fastens onto a car's built-in seat and is used for securing a small child in a car's regular seating position. The seat is removable and is designed to hold the small child safely while riding in the automobile and attaches to a standard seat with hooks or straps and detaches from the standard seat by unhooking the hooks and straps. As referred to herein, the term ‘car seat’ includes a ‘car booster seat’, generally used for a child who has outgrown both an infant car seat and a toddler car seat and lifts the child by several inches. As with an infant car seat, a booster seat is placed on a vehicle adult seat and is designed to restrain the child in the booster seat employing the built-in adult seat belt of the vehicle. A booster seat is generally recommended for children from 40 to 80 pounds. Many booster seats are designed without a back and the child seated on it is lifted by several inches and restrained employing an adult built-in seat belt.
Herein, a person using and/or needing a car seat is referred to as a car seat user. Also, although reference is made to infants, toddlers and/or children, this invention is applicable to any car seat user that uses and/or needs a car seat when traveling in a land, sea or air vehicle. Thus the term ‘car seat’ is used for a removable vehicle seat generally equipped with a restraining device or harness and can be fastened to the seat of a vehicle for securing a person in the vehicle.
It is noted that when seating is required for a plurality of car seat users, a separate car seat is needed for each car seat user. Thus each car seat user uses up a separate regular seat built into the vehicle. Thus a family or group including a plurality of children and/or other car seat users is limited in seating capacity by the adult seating capacity of the vehicle being used. This limitation manifests itself as a serious problem for large families and/or groups that find it difficult to meet children car seat needs for all their children or to meet the needs of car seat users of the group. These families must either not meet car seating requirements or leave one or more children out of the vehicle. It would be advantageous to find a way to better utilize the adult seating capacity in a vehicle to provide more seating for persons in car seats than is provided by the vehicle's adult seating capacity. Besides cars, this may be particularly useful in vans, buses or other land, water or air vehicles.
Definition of Terms
For purposes of this invention:
It is therefore an object of the invention to obviate and/or mitigate disadvantages associated with the use of heretofore conventional car seats in vehicles carrying one or more persons needing use of a car seat when seated in a vehicle.
In a first aspect of the present invention a novel multiple person car seat is provided. The multiple person car seat is such as to provide more proper sitting positions in a vehicle than are provided by the vehicle capacity for persons not in a car seat. Thus, vehicle passenger space widths that are provided for 1, 2, 3 or 4 passengers are used to provide, 2, 3, 4, 5 or more persons respectively, in a multiple person car seat as described below.
In some embodiments of a multiple person car seat, the multiple person car seat uses similar or even greater car width space for car seat users than it takes up for regular the car seat users. In these cases it generally provides more room and comfort advantages than a multiplicity of individual car seats.
In a second aspect of the present invention there is provided a car seat system. The car seat system is modular to enable provision of a desired number of seats for car seat users that are needed and/or fit in the vehicle car seat in which it is incorporated.
In a particular embodiment, the car seat system includes a first car seat right end, a first car seat left end, and a first car seat center. The first car seat center includes a first car seat back, a first car seat base. The first car seat right end includes a support mechanism, designed to accept an attachment mechanism of the right periphery of the first car seat center. The left periphery of the first car seat center includes a support mechanism to accept an attachment mechanism of the first car seat left end when the system is used for a single person. When the car seat system is used for two persons, the support mechanism of the left periphery of the first car seat center accepts an attachment mechanism of a second car seat right end. When the car seat system is used for three persons, the support mechanism of the left periphery of the second car seat center accepts an attachment mechanism of a third car seat right end, and so on. The support mechanism of the left most car seat center accepts an attachment mechanism of the first car seat right end. In some embodiments car seat centers are divided by a separator. The number of car seat centers in a car seat system is limited by the vehicle seat width made available to the car seat system. The car seat system employs at least one adult seat belt male and female connector combination of the vehicle.
In another aspect of the present invention, in a particular embodiment the second car seat center also employs a seat belt of the vehicle. In some cases this may be the same seat belt employed by the first car seat. In some cases this requires use of a seat belt extender to properly restrain the first and second car seats. In some cases there is provided a special seat belt for each car seat to restrain the person in that car seat.
In a further aspect of the present invention, the first and second car seats centers are designed such that when attached together by the support and attachment mechanisms the combined attach seats with car seat right and left ends use a vehicle seat width generally allocated to a single vehicle passenger.
In another aspect of the present invention, the first car seat is designed for a person to face the back of the adult seat and the second car seat is designed for a person to face the front of the adult seat so that the car seat users face each other. The users sit face-to-face. Preferably, each car seat is designed such that the portion of the car seat holding the main body of the person in the seat is wider than the portion of the car seat provided for the legs of the person in that seat. In this way car seat centers have overlapping base portions so as to use a lesser amount of total vehicle seat width space. In general the second car seat center has a second support mechanism to accept a second attachment mechanism of a third car seat center. When the second attachment is coupled to the second support mechanism the second car seat center is in-between the first car seat and third car seat centers.
It is preferable that the vehicle width taken up by the three seat combination [when both car seat 2 and car seat 3 are attached to car seat 1] is no more than the width space taken up by two adjacent adult passenger seats seating two persons without a car seat. In some embodiments, the seating directions of adjacent car seats have the car seat persons facing each other.
It is preferable that both car seat 2 and car seat 3 be designed so that when a person in car seat 2 faces the front of the vehicle seat, the persons in car seats 1 and 3 face the back of the vehicle seat, and when the person in car seat 2 faces the back of the vehicle seat, the persons in car seats 1 and 3 face the front of the vehicle seat.
In a further aspect this invention includes a multiple person car seat. The multiple person car seat is generally designed to provide more seating positions in the vehicle for persons in the multiple person car seat than would be available for persons not in the multiple person car seat.
A two person multiple person car seat is preferably designed to use a vehicle width generally allocated for a single passenger. Three and four multiple person car seats are preferably designed to use a vehicle width allocated for two vehicle passengers not seated in a car seat.
A four or five multiple person car seat is preferably designed to take up a vehicle width allocated for three passengers not seated in a car seat, and so on. Generally, in each design a multiple person car seat generally provides more seating for car seat users than is provided by the vehicle for adult non car seat users, but not in all cases.
In some embodiments, the number of car seat users provided for by the multiple person car seat and/or car seat system is equal to the number of adult car seat users in the same vehicle space width.
As stated, it is preferable that the multiple person car seat be designed such that the seating position of adjacent seats face opposite ends of the vehicle seat. For example, a four person multiple person car seat having seating for a first, second, third and fourth person would provide seating of the first and third persons to face the front of the vehicle car seat, and the seating of the second and fourth persons to face the rear of the vehicle car seat or vice versa. In each case it is preferable that each seating position provides more vehicle width for the body of the person using that seating position than it provides for the leg of that person. This would result in better utilization of the vehicle width space, and would enable more passengers in the vehicle than the vehicle width space allows without the multiple person car seat. The same applies to the car seat system described herein.
Each multiple person car seat generally employs at least a vehicle seat belt to fasten the multiple person car seat to the vehicle. In some cases a seat belt extender is employed together with the vehicle seat belt(s). It is preferable that each seating position have a restraining belt to hold the person in that seating position.
In a further aspect of this invention, in some embodiments adjacent car seats portions are mountable adjustably to use up width not taken by a person in an adjacent car seat portion. Thus, a base of a second car seat uses up a portion of a car seat width available to a first car seat base that is not taken up by a car seat person in the first car seat base of an adjacent car seat. A portion of the second car seat base overlaps a portion of the adjacent first car seat base.
In a still further aspect of the present invention, still more efficient use of vehicle car seat width space is achieved in embodiments having two car seats with users facing each other being seated essentially in a same width space. In these cases two car seats users take up a common portion of vehicle width space that is ordinarily used for a single car seat user. This type of a car seat is herein referred to as a car seat entity for one or more ‘dual person car seats’. A ‘dual person car seat’ can be used as a standalone car seat, a portion of a ‘multiple person car seat’, or as a component of a car seat system.
In a still further aspects of the present invention, there is provided integrated car seat systems enabling storage of a plurality of removably attached car seats on top of one another until needed for use.
In still further aspects of the present invention, there are provided descriptions, advantages and embodiments for dual person car seats, overlapping car seats, changeable car seats, insertable car seats, variable width car seats and multiple person car seats. Some embodiments use a combination of the novelties described herein
The foregoing and further features of the present invention will be more readily understood from the following description of advantageous embodiments, by way of example only, with reference to the accompanying [not to scale]drawings, in which:
The present invention obviates and/or mitigates disadvantages associated with known vehicle car seats. Heretofore, all known car seats provided car seat seating for a single person. Each car seat used-up the vehicle space width allocated to an adult seat. This is disadvantageous to large families or groups that include a plurality of persons needing use of a car seat when seated in a vehicle. This invention provides for car seat systems and/or multiple person car seats that provide more seating positions for persons in a car seat than provided for adults in the car width taken up by the car seats, and/or better seating for car seat users, especially for seating multiple car seat persons in a vehicle.
This invention also provides an integrated car seat system. Often car seats are large and relatively clumsy packages to store with other storage items in a vehicle. Sometimes car seats are mounted in the vehicle even when not all car seats are used. This unnecessarily limits seating of regular vehicle passengers. An integrated car seat system solves this problem by only providing and using car seat position when actually needed by a car seat user. It also eleviates the problem of storing unused car seats in the vehicle storage when these are unused.
The integrated system is formed to provide two or more car seat being colocated on top of one another. Car seats within an intergrated system are removably attached to one another. When the integrated system is in a closed state, it provides a single sitting position for a singular car seat user sitting in a first car seat of the integrated system. When a second sitting position is needed for a second car seat user, a second car seat is separated from the integrated system. If a third car seat is included in the integrated system, that car seat is separated out from the first and/or second car seat to provide a seating position for a third car seat user, etc.
In general, the car seats systems, the integrated car seat systems and/or multiple person car seats of the present invention may provide any or all of the amenities of previously known car seats. The present invention is thus useable to provide features and general aspects of standard prior and developing car seat technology. It is upon this technology that the present invention is providing special features described herein.
In the following the words ‘right’ and ‘left’ are used to facilitate understanding of embodiments presented herein. This is not to be considered a needed limitation, and ‘right’ and ‘left’ may be interchanged in accordance with a particular implementation. The particular implementations are only exemplary enablements, in so much that the concepts and advantages may be achieved by other implementations which are also deemed to be included and protected by the claims of this invention.
In a first embodiment, the present invention provides novel vehicle seating systems. A car seat system is modular to enable provision of the number of seats for car seat users that fit in the vehicle car seat in which it is incorporated. This enables purchasers to purchase that portion needed at a particular time. Additional or replacement portions of the system may be purchased for example as a family size increases.
The novel car seat systems are generally such as to provide more proper sitting positions in a vehicle than are provided by the vehicle for persons not in a car seat. Thus, vehicle passenger space widths that are provided for 1, 2, 3 or 4 passengers are used to provide, 2, 3, 4, 5 or more persons in a multiple person car seat as described in this description. This overcomes problems with the present state of the art of using a car seat to provide seating for example an infant or a child within the same car width provided for an adult passenger. There are many large families, or family groups traveling together in one vehicle for whom the one-to-one passenger space width allocation does not provide sufficient safe and proper seating for the entire family and/or group.
In some embodiments multiple person car seat provides for seating of the same number of car seat users as provided for regular seat users without the adjacent walls inherent to two or three prior art adjacent car seats. In some embodiments a separator is provided between adjacent car seat portions to provide some separation of adjacent car seat persons.
In
Each of the three seating positions in vehicle seat 110 generally takes up one third of the entire seating width shown as ‘W1’, ‘W2’ or ‘W3’. Generally, car seat 105 takes up at least one entire seating width, ‘W2’. If a second car seat was used it would take up the width ‘W1’ or ‘W3’. A third car seat when used would take up the width ‘W3’ or ‘W1’ whichever is not used for the first and second car seats. In some cases a car seat is designed with extra side cushioning and apparatus that takes up more than an adult seat width such that a vehicle having a vehicle seat designed for three adults fails to provide space width for three separate car seats. This invention overcomes this problem and provides more seating for car seat users than provided for adult passengers in a vehicle seat. Although the portions of the car seat in
In a first aspect of the present invention there is provided a first car seat center 205A shown in
The right side car seat end 210 includes a car seat support mechanism 220 that is designed to mate with a right side attachment mechanism 225A on first car seat center 205A. The left side car seat end 215 has a left side attachment mechanism 235 that is designed to mate with a left side support mechanism 230A of first car seat 205A. When the car seat system is used as a single car seat, it includes first car seat center 205A, right side car seat end 210 and left side car seat end 215.
Car seat center 205A is generally formed to have a car seat back 206A and a car seat base 207A. In some embodiments car seat back 206A and car seat base 207A are made as an integral unit. Car seat back 206A has indentations 208A and 209A that may be used to accept at least one belt of a vehicle belt pair of the vehicle upon which it is mounted. Car seat center 205A often includes a car seat center belt and/or harness (not shown) to restrain a person seated in car seat center 205A. Car seat base 207A often has two indentations 211A on its right side and two indentations 212A on its left side. Indentation 211A and 212A are made to accept a car seat separator 310 shown in
When a car seat separator 310 is used it provides some physical separation between persons sitting in adjacent car seat centers. Car seat separators 211A and/or 212A are used for car seat centers that are adjacent and attached to each other. Indentations 211A need not be used when car seat center 205A is attached or is integral to right side car seat end 210. In a preferred embodiment right side car seat end 210 and first car seat center 205A are formed to be an integral unit.
The car seat system 200 is made to be two person car seat by connecting a second car seat center 205B between first car seat enter 205A and [another car seat not shown or to] left side car seat end 215. As shown in
Second car seat center 205B is generally formed to have a second car seat back 206B and a second car seat base 207B. In some embodiments second car seat back 206B and second car seat base 207B are made as an integral unit. Second car seat back 206B may have indentations 208B and 209B that are used to accept at least one belt of a vehicle belt pair of the vehicle upon which it is mounted.
Second car seat center 205B includes a second car seat attachment mechanism 225B that is designed to mate with support mechanism 230A of first car seat 205A. Second car seat center 205B has a second car seat support mechanism 230B that is designed to mate with another attachment mechanism. Car seat center 206B often includes a car seat center belt and/or harness (not shown) to restrain a person seated in car seat center 205B. Car seat base 207B often has two indentations 211B on its right side and two indentations 212B on its left side. Indentation 211B and 212B are made to accept a car seat separator 310 shown in
In similar fashion the car seat system 200 becomes a three person car seat by connecting another car seat center [not shown] between second car seat center 205B and left side car seat end 215. As stated above, in a preferred embodiment left side car seat end 215 is formed to be an integral unit with second car seat center 205B, and so on. In this case the car seat system 200 is made into a three person car seat by inserting another car seat between the first car seat center 205A and the second seat center 205B, and so on.
Although
Generally, the car seat ends and centers are designed to use less vehicle seat ‘space width’ than the seat width allotted to an adult seat for each car seat user seating. It is preferable that when the car seat system 200 provides seating for two persons its total use of vehicle seat width be not much more than used by a single adult seat. In this way when the two seat car seat system is mounted in a vehicle seat designed for two adult passengers, it leaves room for an adult passenger even after it is mounted in the vehicle seat. Similarly, when the two seat car seat system is used in a vehicle seat designed for three adult passengers, it leaves room for two adult passengers.
As shown in
Car seat center 205B has a first side having indentations 211B and a second side having indentations 212B. The first side of car seat center 205A is attached to right side car seat end 210. The second side of car seat center 205A is attached to the first side of car seat center 205B. The second side of car seat center 205B is attached to the first side of another car seat center (not shown), or to left side end 215. End 210 is sometimes referred to as being a first side end. End 215 is sometimes referred to as being a second side end.
Other embodiments have other implementations than the method shown in the present figures for meeting concepts satisfied by the indentations, separator, support and attachment mechanisms according to car system designs. Some of these are not always used. Also, the support and attachment mechanisms need not be the same for all car seat centers and car seat ends. This depends on the car seat system design. These mechanisms need not be on the sides of the car seat centers as shown in
Generally, car seats are variously designed wherein the person in the car seat faces either the front or rear of the vehicle car seat. Thus although the above described car seat system shown in
Car seat centers are designed to couple car seat centers together using a compatible pair of support mechanism and attachment mechanisms. Attachment mechanisms are designed to mate with a support mechanism. These mechanisms variously employ pins, sliding, connecting, mechanical, magnetic and/or electrical means. Although these mechanism are shown in
In some embodiments of the present invention, the second, third, and/or fourth car seat centers also employ a seat belt of the vehicle. In some cases this may be the same seat belt employed by the first car seat. In some cases this requires use of a seat belt extender to properly restrain the first, second and third car seats. In some cases there is further provided a special seat belt and/or harness for each car seat to restrain the person in that car seat center.
As previously stated, it is known in the art that car seats are designed that have the car seat person in the car seat to face the front of the car vehicle seat, whereas others car seats are designed that have the car seat person in the car seat to face the rear of the car vehicle seat. This variation is particularly useful in the present invention, which provides for seating of car seat persons face-to-face, where at least one card seat person faces the front of the car vehicle seat, whereas at least one others car seat person faces the rear of the vehicle seat.
In a particular aspect of the present invention, the first and second car seat centers are designed such that when attached together by the support and attachment mechanisms the combined attach seats use a vehicle seat width generally allocated to a single vehicle passenger.
Consideration is now directed to design of the car seat base, 207A, and 207B of
It is advantageous to implement the car seat system in which car seat bases 4B and 4C are used alternately. In some embodiments, a first car seat center uses modified trapezoidal car seat bases 4D or 4F and/or at least one car seat center uses modified trapezoidal car seat base 4E or 4G. Alternating different car seat bases may advantageously be employed with bases being inline with each other as in 4H, or by offsetting the car seat bases as in 4I. Extra wide base 4J is used to provide extra width space for a car seat user needing extra width space, for example as is needed for an obese child or handicapped car seat user. In all these cases, the car seat center is designed to be compatible with the car seat base used. When the car seat base is for a booster seat, the car seat center back is often minimized or not used.
Generally, when a seating position of a car seat system is allocated to a booster seat the car seat center has no car seat back. In some implementations a car seat system combines car seat centers with and without backs. The back of a person using a booster seat would generally be on the vehicle seat back and facing the seat front to allow the booster seat user to dangle his/her legs. A person sitting adjacent to the booster seat person would advantageously be placed on a seat base facing the seat back. Booster seat users may also be placed adjacent to each other using seat bases as appropriate to that seating.
Preferably, each car seat is designed such that the portion of the car seat holding the main body of the person in the seat is wider than the portion of the car seat provided for the legs of the person in the seat. Preferred variations provide that when a first car seat center is a booster seat, the second car seat is an infant seat.
In a further aspect the first car seat has a second support mechanism to accept a second attachment mechanism of a third car seat. When the second attachment is coupled to the second support mechanism the second car seat is on one side of the first car seat and third car seat is on the other side of the first car seat.
It is preferable that the vehicle width taken up by the three seat combination (when both car seat 2 and car seat 3 are attached to car seat) is less than the width of 2 adjacent passenger seats seating persons without a car seat.
It is preferable that both car seat 2 and car seat 3 be designed so that when a person in car seat 1 faces the front of the vehicle, the persons in car seats 2 and 3 face the back of the vehicle, and when the person in car seat 1 faces the back of the vehicle, the persons in car seats 2 and 3 face the front of the vehicle.
In a further aspect this invention includes a multiple person car seat. The multiple person car seat is designed that it provides more seating positions in the vehicle for persons in the multiple person car seat than would be available for persons not in a car seat. A two person car seat is preferably designed to use a vehicle width allocated for a passenger with generally provided for a single passenger. Three and four multiple person car seats are preferable designed to use a vehicle width allocated for two vehicle passengers not seated in a car seat. A four or five multiple person car seat is preferable designed to take up a vehicle width allocated for three passengers not seated in a car seat, and so on. In each design of a multiple person car seat it is advantageous that the car seat provides more seats for car seat users in a seat width, than is provided by the vehicle width space for adult passengers in the vehicle seat in the vehicle.
It is preferable that the multiple person car seat be designed such that the seating position of adjacent seats face opposite ends of the vehicle seat in which it is mounted. For example, a four person seat having seating for a first, second, third and fourth person multiple person car seat would provide seating of the first and third persons to face the front and the second seating of the second and fourth persons facing the rear. In each case it is preferable that each seating position provides more vehicle width for the body of the person using that seating position than it provides for the leg of that person. This would result in more efficient utilization of the vehicle width space, and would enable more passengers in the vehicle than the vehicle width space allows without the multiple person car seat. This is also so for the car seat system described herein.
Each multiple person car seat employs at least a vehicle seat belt to fasten the multiple person car seat to the vehicle. In some cases a seat belt extender is employed together with the vehicle seat belt(s). It is preferable that each seating position have a restraining belt to hold a person in that seating position.
In general, multiple person car seats are designed to provide any combination of car seat centers of the described above for car seat systems.
It is noted that the support and attachment mechanism may be implemented in ways known previously for connecting two parts. This includes but is not limited to pin and insert mechanisms, sliding mechanisms, male to female mating connections, sexless connection mechanisms, etc. In some embodiments, these connections require and/or employ a connection release mechanism to disconnect attached seats or are disconnected manually. These implementations are best chosen to satisfy particular car seat implementation requirements.
In some embodiments adjacent car seats portions are mountable adjustably to use up width not taken by a person in an adjacent car seat portion. Thus, a base of a second car seat uses up a portion of a car seat width available to a first car seat base that is not taken up by a car seat person in the first car seat base of an adjacent car seat. An example of this is shown in
In a still improved embodiment, there is made available car seat bases which have both receiving holes and wing inserts. An example of this is shown in
In some embodiments a base type as is shown for base 680 is used. Here, the upper group of receiving holes is combined into a large hole 685 and the lower group of receiving holes is combined into a large hole 690 through which the wing inserts slide and are locked into a desired seat width. In some embodiments, a separator 670 is also provided to separate the persons in car seat base 620 from the person in car seat 680 when desired.
In general embodiments, receiving holes may be used to act as a support mechanism and insert wings may be used to act as an attachment mechanism. Actual implementations of wing inserts and/or receiving holes may use any available known interconnecting mechanism, especially those useable for support and attachment mechanisms. Other methods are also available to provide ways of implementing the seat to achieve the objectives using the concepts described herein.
Still better use of vehicle car seat width is achieved in embodiments having two car seats facing each other. In this case two car seats users take up a common portion of vehicle space width that is ordinarily used for a single car seat user. This type of a car seat is herein referred to as a car seat entity for a ‘dual person car seat’, seating two car seat users face to face. A ‘dual person car seat’ can be used as a standalone car seat or as a component of a car seat system. It can also be implemented as a component within a multiple person car seat.
Multiple use of face to face car seats as in a ‘dual person car seat’ provides more room for seating additional car seat users in limited vehicle space width. This is possible since some vehicles are such to allow these extremely advantageous embodiments. In these vehicles there is sufficient room in front of a vehicle seat to allow car seats to be mounted face to face as shown in
Car seat base 730 is a base of a first car seat center 700 that includes car seat back 735. Car seat base 770 is a base of a second car seat center 750 having car seat back 760. The bases 730 and 770 of these centers are mounted face to face between two vehicle seats 710 and 720. In some embodiments the base and back of the car seat centers are integral with each other. Other embodiments are also appropriate using these concepts.
In the example embodiment shown car seat 700 mounted on the front of vehicle seat 710 and is supported using supports 740 and 745. Car seat 750 is mounted at the back of vehicle seat 720 and is supported using supports 780 and 790. In the embodiment of
In some embodiments of face to face or, the face to face car seats are mechanically connected to each other and need not make use of vehicle seat mounting. For example, these types of car seats often only need to make use of the vehicle provided adult seat belts with or without a seat belt extender. In these as with other embodiments in this application, the car seat back and the car seat base may be an integral unit. Also, these car seats may generally have at least one car seat end. In some cases the dual person car seats are formed integral with at least one end.
It was shown that it is most advantageous to design multiple person car seats to provide more room for car seat users than is available in a same width space. However, some embodiments of multiple person car seats actually provide seating space for a car seat user that essentially uses the same width space as used for regular adult passengers. These may be implemented in any of the ways described above. This is advantageous in so much that it provides features of previously known car seats with increased room for car seat persons in the multiple person car seat or car seat system. It reduces the requirements of having both left and right car seat sides for each car seat person. Car seat sides are sometimes referred to as car seat walls. Car seat sides may not always be required between car seat persons. A separator is sometimes useful between car seat persons. The separator need not be as wide as the two adjacent car seat sides it is replacing when two separate adjacent car seats are used.
For example, in some embodiments a multiple person car seat for two car seat users advantageously uses the entire width space allotted for adjacent regular passengers of a vehicle. When two separate car seats are used as heretofore required for two car seat users, each separate car seat has its own right and left side sides [walls]. There are two car seat sides [walls] adjacent to each other. A multiple car seat for the two car seat users eliminates the need for the adjacent side walls between the two car seat users. In this case the two car seat users will each have more space and comfort for a multiple person car seat or car seat system designed for two than in prior art separate car seats. If necessary or desired the two car seat users in the multiple person car seat or car seat system designed for two may include a separator between the two car seat persons. A same advantage is achieved in a multiple person car seat or car seat system designed for three etc.
In still other embodiments a multiple person car seat or car seat system designed for two or more car seat persons is embodied to provide at least one very wide car seat base for meeting special requirements of a special car seat user. Some embodiments use a combination of car seat bases that are each wider, equal to or narrower than the car space width provided for a regular passenger in a regular vehicle seat. This depends on each particular need and application.

The bases may be any of the bases described above. and/or is a shape wherein less car width is provided for the car seat user's legs, than is provided for the car seat user's head-ward direction, so that the total car seat system employs less vehicle seat width.
Thus,
Any of the many ways known to those in the art can be used to attach a seat to another. A novel attachment mechanism is shown in
Fingers 1031 of seat 1030 are lowered to mate with fingers 1013 of seat 1010. Mating the male fingers of one seat with the female fingers of the adjacent seat causes seat-to-seat capture to secure one seat to another. The seats can be separated by lifting the fingers of one seat above the fingers of the seat to which it is attached.
It is noted that a two seat system may be formed to attach seat 1020 to seat 1030 by inserting male fingers 1031 between female fingers 1026. Although not shown a booster seat may also be formed to have male fingers on one of its sides and female fingers on its other side.
Although infant seat 1010 is shown for a frontward facing car seat user, it can similarly be implemented for a rearward facing car seat user. The number of car seat positions may be increased by adding one or more car seats having both male and female fingers as shown for car seat 1010. In some embodiments a plurality of car seats of a car seat system have both male and female fingers as does seat 1010, to allow attachment of another car seat to either or both of that car seat's sides.
It is noted that generally each booster seat has a receiving mechanism for receiving a lap/shoulder belt system. This sometimes uses the belt of the vehicle with an extension as required by the seat design.
Further car seat embodiments are provided that enable the insertion of one car seat type insert into another car seat type. This allows changing a booster seat to an infant seat by inserting an infant seat insert into the booster seat. It also allows changing a forward facing car seat to a rearward facing car seat as for example to satisfy particular car seat type combinations for different age children as desired and/or required by a particular use situation according to desire of for example a parent or a vehicle driver. Referring to
As in
Thus, although
Also as with
It is noted that in some embodiments there is a combination of only two individual seats. This may be two individual booster seats, two individual infant seats or one infant seat and one booster seat. Although the infant seat shown is forward facing in these example embodiments, any or all of the infant seats may be rearward facing. As described, the head of a car seat user in a forward facing car seat is close to or leaning against the vehicle seat back of the vehicle seat in which the car seat is mounted, and the legs of the car seat users are directed towards the front of that vehicle seat. The head and legs of the car seat user in a rearward facing car seat are reversed.
As previously described, it is often advantageous to enable, for example, a parent of users of a car seat to change the types and/or configuration of one or more the seats provided in a car seat system. This is embodied by allowing insertion of a car seat insert to change the type of car seat in a particular car seat user position.
The ability to change from and to one car seat type to another car seat type is advantageous even for a single car seat. In this embodiment this is accomplished by addition or removal of an insert to the car seat. Thus a booster car seat can be charged to either a forward facing or a rearward facing car seat. A forward facing car seat can be changed to a rearward facing car seat.
In order to form a two position car seat system booster seat 1340 is attached to car seat 1330 by interconnecting male fingers 1344 of car seat 1340 with female fingers 1336 of car seat 1330. This provides a two seat car seat system for one infant seat user and one booster seat user. When booster seat 1340 is attached to car seat 1330, the booster seat can be changed to provide seating for second infant seat user by inserting car seat insert 1310 over booster seat 1340. This is accomplished by inserting insert mechanisms 1314 and 1316 of car seat 1310 into receiving mechanism 1346 of booster seat 1340 respectively.
In similar fashion, booster seat 1320 can be attached to infant seat 1330 by inserting male fingers 1338 of seat 1330 into female fingers 1326 of booster seat 1320. When booster seat 1340 is also attached to infant seat 1330, this forms a car seat system with three seating positions. In like manner, booster seat can be changed to provide seating for an infant by inserting a car seat insert such as 1310 into booster seat 1320 by inserting infant seat 1310 insert mechanisms 1314 and 1316 of infant seat 1310 into receiving mechanism 1322 of booster seat 1320 and into receiving mechanism 1332 of infant seat 1330. In like manner, positions may be made for 4, 5, 6, etc car seat users. This is particularly useful in a large van, bus or water vehicle.
This novel concept is also useful to change all seats of the three seat car system formed by seats 1320, 1330 and 1340 to provide seating for three infants by using two car seat inserts such as car seat insert 1310. It is noted that although seat insert 1310 is shown as a rearward facing insert, this concept is similarly applicable to a forward facing insert. Thus this concept is useful to reversibly change a single car seat or any number of car seats of a car seat system to-and-from a booster seat to a forward or rearward facing infant seat and/or a forward facing changing seat to a rearward facing infant seat. Use of the insert mechanisms described is just another example of a novel method to connect a car seat insert into a car seat.
Thus in accordance with the present invention there is provided an insertable car seat module which includes a receiving car seat of a first type having receiving mechanism to receive a car seat insert. The car seat insert has inserting mechanism to couple with the receiving mechanism and changing the first type car seat to a second type car seat.
It is noted that for a typical three position car seat system or multiple car seat as shown in
It is further noted that other methods of inserting a car seat insert into a car seat may be used employing the concepts of this invention. Some embodiments enable insertion of a plurality of car seat inserts into a car seat system and/or a multiple car seat. Generally, car seat inserts are removable to enable continued usage of the car seat into which it is inserted to revert back to its original form and use. In some cases insertion of the car seat insert is purposely made to be permanent according to a particular application where it is used.
It is still further noted that the concept of inserting a car seat into another car seat is also advantageously used with any singular car seat. Almost any existing or to be manufactured car seat can be used to be a receiving car seat. Generally, this is accomplished by providing either a specific or universal insert receiver for that receiving car seat. This allows the capability to advantageous change any car seat to provide a desired use of that car seat which is only available by providing that car seat with a car seat insert. In some embodiments an insertable car seat is designed to have universal insert mechanism allowing it to be inserted into almost any singular car seat. In some embodiments a insert receiving car seat is designed to have universal receiving mechanism allowing it to receive almost any insertable car seat.
Thus, it is further noted that an insertable car seat can be used with any single or multiple car seat of any manufacturer, make or model. Just as the concept of an insertable car seat can be used to change a forward facing car seat to a backward facing car seat it can be used to change a backward facing car seat to a forward facing car seat. This uses an interconnecting mechanism formed for the car seat that is receiving the insertable car seat being compatible with the mechanism of the insertable car seat.
A still further advantageous concept of this invention is the provision of a car seat having variable width. In this way, a particular car seat user has the ability to use only the amount of vehicle seat width space necessary for that particular car seat user. The available width adjustment is advantageously made to range from less than a standard infant or child width requirement to more than the standard width requirement. Typically this may range of width adjustment from 9 to 16 inches. More or less width adjustment is useful for some applications, especially for car seat users that are very small, very broad and/or handicapped.
In one case, the two base portions brought together should be viewed as a variable width booster seat. Addition of left and right of seat back portions 1430 and 1440 make the seats useful for infants. Control mechanism 1424 also controls. A base cover mat, not shown, makes the seat comfortable.
An alternate embodiment of a variable width base seat is shown in
Use of variable width base portions 1460 and 1480 are also useful for a singular booster seat. In order to form a variable width infant seat left and right back portions 1450 and 1470 are used. Left back portion 1450 includes extension 1451 and protrusion 1455. Right side back portion 1470 includes extension 1472 and slot 1475. Slot 1475 receives protrusion 1472 movement of 1450 over 1470 either manually or as controlled by gear box 1452. When used year box 1452 is also driven by control 1461.
An alternate embodiment of variable car seat width provides provision to slide one car back and/or base portion to be set by sliding one portion over the other car portion. This may be manually controlled in about one half inch increments. In one embodiment the two base portions are connected together by an accordion type section, with the accordion being let out or pulled in to widen or narrow the car seat width.
Some embodiments of a multiple car seat employ the technique shown in
It is further noted that variable width single or multiple car seat using the concept of
It is noted that a car seat system can be a combination of one or more regular width, car seat bases combined with one or more variable width car seat bases, all regular bases or all variable width bases as required and/or desired in a particular application. A multiple integral car seat can also provide variable width for any or all of its car seat positions. This would allow car seat position width to be shared and set according to the width of the actual car seat users in a particular usage situation.
It is noted that this variable base width concept is described considering only the car seat base and/or center portion of a car seat. This may be as shown for example for car seat centers 205A or 205B of
In still a further advantageous concept, the present invention provides car seat designs for car seats that can be reversibly changed from one car seat type to at least one other car seat type. In this context, a booster seat, a forward facing infant seat, a rearward facing infant seat are said to be of a different ‘type’. The word ‘changeable’ is used is used to mean changing from one ‘type to another ‘type. Thus a changeable car seat can be changed from a booster seat into either a forward facing infant seat, a rearward facing infant seat, or into both a forward and rearward facing infant seat.
A changeable car seat is said to have different states, each state being for a different type car seat and/or a different car seat configuration.
It is noted that use of a hinge is just one of many embodiments. The word hinge as used herein is meant to illustrate a means of coupling components. It is understood that the word hinge refers to a coupling.or coupling mechanism. This could a hinge, a snap, a hook and eye, a strap, a bracing member, a material attachment and/or a combination of these or the like. Thus, in some embodiments some or all of the components are connected by a connecting material, hooks, snaps, zippers, braces and/or straps and any coupling device or method. This is in place of or in combination with using hinges. In some cases the components are held in a particular desirable position by metal or a suitable material.
In some embodiments of a changeable car seat when the seat is opened to be an infant seat, the seat can be selectively mounted as either a car seat in which the car seat user faces frontward or rearward. This is generally accomplished by provision of selective vehicle seat belt insertion into the changeable car. Other embodiments would also satisfy the concept of a changeable car seat.
In some embodiments the upper back portion is in open position shown in
Thus, an advantageous embodiment of a changeable car seat includes: a base having a first, second, third and fourth side. The changeable car seat also includes a left side end coupled to the first side; a lower back, portion coupled to the second side; a lower right side portion end coupled to the third side; a upper leg portion coupled to the fourth side; and setting mechanism for forming an infant seat from the components in an open state, allowing formation of a booster seat. The components of the changeable car seat can be folded in a closed state together to form the booster seat. It includes a seat belt attachment allowing formation of either or both a forward facing and a rearward position. It sometimes includes a lower leg portion coupled to the upper leg portion opposite the base; an upper back portion coupled to the lower back portion opposite said base; an upper right side end coupled to said lower right side end opposite the base.
Other embodiments of the changeable car seat do not use all the components shown and are still included in this invention as using the concept of this invention. Changeable seat components are sometimes held in a particular new or old state or desirable position using straps, snaps, hooks and eyes, belts, braces, supporting braces and the like, or any combination of these.
In some embodiments, couplings are taken from any combination of couplings including: soft or semi-rigid material folding a pair of coupled changeable car seat component to be coupled in any of several desired positions; a hinge coupling; semi-rigid coupling. The coupling allows the changeable car seat to also be set as a booster seat. Sometimes some or all of the components of the changeable car seat are formed as an integral unit. These are also useable in some embodiments of the integrated car seat system for making seat members removably attachable.
As stated car seat 1100 may also be viewed as three individual car seats attached to each other or as a multiple car seat with three positions.
In an example embodiment the entire width of seat 100 is less than forty inches, which leaves adequate seating for a regular passenger in a vehicle seat 1640.
In same embodiment the car seat system or multiple car seat is designed to provide seating for four or five car seat users in the vehicle space width provided by vehicle seat 1620, 1630 and 1640. The concept of variable width car seat base is advantageously employed to provide useful widths for a particular mix of car seat users in a two, three, four or five position car seat system. The number of car seat user positions in a car seat system or a multiple car seat is only limited by available vehicle space width.
Seat 1710 shows an upper booster seat, with belt seat attachments 1715 and 1716. Seat 1720 shows an lower booster seat 1720, with seat belt attachment mechanism 1725 in a lowered position. In some embodiments seat 1710 and/or seat 1720 form infant seats having attachment mechanism 1715, 1716 in an up position particularly useful for a forward facing or a rearward facing infant seat.
In the embodiment shown, seat 1760 has a back portion 1762, side portions 1764 and 1766 and base portion 1768. Seat 1770 has a back portion 1772, side portions 1774 and 1776, and a base portion 1778. Seat 1780 has a back portion 1782, side portions 1784 and 1786, and a base portion 1788.
Seats 1760, 1770 and 1780 are formed in a single package to provide seating for a single car seat user in seat 1780. The seat to seat attachment mechanism is such to allow the seats to be separated from the integrated package to provide seating for two or three car seat users.
In some embodiment either seat 1760 and/or seat 1780 is a booster seat. As with all seat back to seat base attachments in some embodiments the back portions are inclined backward forming an obtuse angle with its base rather than in a vertical position forming a right angle with its base. This provides better seating for a small infant.
Many embodiments use a pad covering the back and base portions for seating comfort.
Each seat position making up an integrated car seat system is herein referred as a member seat. Each member seat has either or both, a capture mechanism to capture another seat member and/or an attachment mechanism to allow it to be captured by a capture mechanism of another member seat. The capture mechanism is coupled with a release mechanism to allow release of a captured member seat. These mechanisms may be formed in any capture/release mechanism known to those familiar with the capture/release art. The mechanisms may include simple or complex mechanisms or even force fit and or snap/unsnap release mechanisms.
In a preferred embodiment all seat members of an integrated car seat are identical. Each seat is formed to be able to capture a member seat and also be captured by another member seat. Thus each member seat includes capture/release mechanism and attachment mechanism. This design allows the integration of many identical seats. This is generally limited by height and space consideration. In some cases a first car seat of the integral unit has only capture and release mechanisms to capture, release and recapture an integrated seat member.
Member seats of integrated car seat systems are removably attached using any known method for attachment, release and reattachment. These include force fitting, straps, snaps, springs, hooks and eyes, belts, braces, supporting braces and the like, or any combination of these.
It is noted that generally each seat in an integrated seat car system is a self contained car seat capable of being mounted in the vehicle seat to provide seating for a car seat user. In some case external hardware and/or components are used.
In another embodiment of an integrated car seat system, each car seat member seat is formed having a plurality of components. In this case, a member car seat includes a member seat base and a member seat upper portion. Sometimes a first member car seat is an integral car seat. Other times any member seat may be used as the first member car seat. All member seat base portions removably attached to the base of the first car seat are one on top of another, and all member seat upper portions are removably attached to the upper portion of the first member car seat.
Sometimes a member car seat base includes member seat right and left ends. Sometimes it also includes a portion to be formed as a back for a rearward facing car seat position. Sometimes the member seat upper portion includes a member seat back particularly when used as a forward facing car seat position. In some cases at least one of the member seat upper right and left ends and member seat back are folded within the member seat base and upper portion respectively to obtain a reduced package. This is shown in
Changeable seat 2030 is changeable from a booster seat without sides to a booster seat with sides by unfolding its sides using hinges 2032 and 2036. Changeable seat 2030 is further changeable from a booster seat without a back to a booster seat with a back by unfolding its back 2050. Changeable car seat 2010 is changeable from a booster seat without a back to a booster seat with either a half back or a full back by unfolding its back 2015 halfway or completely as shown in
In some embodiments the first member car seat is a pre-existing, or to be manufactured car seat into which car members are packaged as disclosed in this invention. This in general, almost any particular car seat of any manufacturer and model can act as the first car seat of an integrated car seat system. This includes individual infant car seats, booster car seats and multiple car seats of any manufacturer. This is accomplished by adapting one or more integrated member car seats to be placed under the base portion and/or on top of the upper portion of the particular car seat. In some cases a two piece integrated car seat member is used with the member seat base being removably attached under the particular car seat and the member seat upper portions removably attached to an upper portion of the particular car seat.
In some embodiments of any of the car seat seats and/or systems, external mounting hardware and/or components are used for mounting one integrated car seat member to another and/or for mounting an individual removed car seat member to the vehicle seat.
It is noted that generally any manufactured booster seat and any manufactured infant or other car seat can be made to accommodate one or more seats placed under or above that manufactured seats.
It is further noted that in many cases, individual car seat positions of a car seat in a car seat system, a multiple car seat and an integrated car seat system are often capable of receiving an attachable tray. The tray may be used for aiding child feeding and/or providing game and/or playing objects etc.
Generally, a single car seat is packaged as a single car seat to provide seating for a single car seat user. A multiple car seat is packaged as a plurality of car seats to provide simultaneous seating of a plurality of car seat users in seats adjacent to each other. An integrated car seat is packaged as a plurality of car seats atop one another. As initially packaged it provide seating for a single car a seat user. It provides additional seating for other car seat users only in seats that are removed from the initial integral package.
In some embodiments, there is a combination of multiple seats with integrated seats. For example lets consider at least one (or all) of the three seats multiple package shown in
In some embodiments the first member car seat is a pre-existing carseat, or to be manufactured car seat, into which car member car seats are packaged as disclosed in this invention. Thus in general, almost any particular car seat of any manufacturer and model can act as the first car seat of an integrated car seat system. This includes individual infant car seats, booster car seats and multiple car seat of any manufacturer. This is accomplished by adapting one or more integrated member car seats to be placed under the base portion and/or on top of the upper portion of the particular car seat. In some cases two piece integrated car seat members is used with the bases removably attached under the particular car seat and the member seat upper portions removably attached to an upper portion of the particular car seat.
In another embodiment of an integrated car seat system, each car seat member seat is formed to include a member seat base and a member seat upper portion. Sometimes a first member car seat remains in the integral unit. Other times, any member seat may be used as the first car seat. All member car seat bases are removably attached to the base of the first member car seat one on top of another, and all member seat upper portions are removably attached to the upper portion of the first member car seat one on top of another.
Sometimes, a member car seat bases includes member seat right and left ends. Sometimes it also includes a portion to be formed as a back for a rearward facing car seat position. Sometimes the member seat upper portion includes a member seat back particularly when used as a forward facing car seat position. In some cases at least one of the member seat upper right and left ends and member seat back are folded within the member seat base and upper portion respectively to obtain a reduced package.
As previously stated, in some embodiments external mounting hardware and/or components are used for mounting one integrated car seat member to another and/or for mounting an individual removed car seat member to the vehicle seat.
It is noted that generally any manufactured booster seat and any manufactured infant car seat can be made to accommodate one or more seats placed under or above that manufactured seat. It is preferred to removably attach booster seats under any manufactured seat, especially when the manufactured seat is an integral multiple car seat. In this case, a number of member car seats are mountable under the multiple car seat. However, even in this case integrated member car seats may be mounted above any or all car seat positions in an integral or non-integral multiple car seat.
The novel car seat concepts described above may also be used together or separately in order to get the best advantage for a particular user requirement. The particular embodiments described and/or shown are to be considered as illustrating the particular concept and should not be considered to limit the concept to particular description and/or drawing. Thus, any embodiment using any of these concepts are included as being protected by this invention as claimed herein.
Thus, although this description uses words like ‘car’, ‘vehicle’, ‘car seat’, etc, it should not be limited by these words. This invention is similarly applicable to seating ‘car seat users’ in air, water and other land vehicles, etc. The singular car seats, car seat systems and multiple person car seats of this invention are applicable to booster seat and non booster seat combinations. The vehicle of the present invention may be any land vehicle, any air vehicle or any water vehicle.
It is still further noted that the particular implementations described above should only be considered as specific examples of enabling implementations of the concepts and novelties of this invention. Other implementations are also suitable to use the concepts of this invention to obtain the advantages of this invention. These include locations and types of support and attachment mechanism and/or the separator, the car seat sides, car seat insert and insert mechanisms, variable width seat backs and or seat bases of car seat centers and width control or setting mechanisms, and/or multiple person car seats, modularity of certain parts, car seat entities, dual car seats, etc. These and other implementations are similarly protected by the claims and concepts of this invention.
