The present disclosure relates to vehicle seats connected to a chassis or frame of a vehicle. More particularly, the present disclosure relates to vehicle seats with connections for safety car seats. The safety car seats may be for infants or toddlers, although they are not limited thereto.
The most common cause of death for children aged 1-5 in developed countries is by accident, and the leading cause of death by accident is car accidents. When properly installed in passenger cars, child safety seats have been reported to reduce fatal injury by about 71% for children (i.e., infants) under age one and by about 54% for toddlers aged 1-4. Nonetheless, in the U.S. alone, over 250 children aged 0-4 are fatally injured every year while properly restrained in their car seats.
In addition, to the fatalities, every year, thousands of children who are properly restrained in car seats still sustain incapacitating injuries resulting from car accidents. By far the most common severe injuries are head injuries, including cerebrum injuries (contusions or lacerations), concussions, skull vault and skull base fractures, subarachnoid hemorrhages, and subdural hematomas. Other common severe injuries are thoracic (lung and rib), abdominal (bowel, liver, spleen, kidney), spine, and upper extremity (clavicle, humerus, radius/ulna) and lower extremity (pelvis, femur, tibia/fibula) injuries. The injury outcome in children can be worse than similar injuries sustained by adults, and children who suffer traumatic brain injuries can experience lasting or late-appearing neuropsychological problems. For example, frontal lobe functions develop relatively late in a child's growth, so that injury to the frontal lobes may not become apparent until the child reaches adolescence.
According to the U.S. National Highway Traffic and Safety Administration (NHTSA), children under the age of one should always ride in a rear-facing car seat that has a harness. While it is recommended that rear-facing seats be used as long as possible, it is recognized that children aged 1 and over will wish to face forward. NHTSA recommends that children aged 1-3 (and older if they have not reached a certain height and weight) use a forward-facing car seat with a harness and tether that limits the child's forward movement during a crash.
There are many types of car seats available for purchase. Infant seats recommended for children under age 1 are rear-facing. Many include a base that is belted or tethered into the car and a seat that can latch into the base. The seat often includes a handle so that the seat may be carried when it is unlatched from the base (i.e., from the car). A popular car seat option for infants as well as children is a “convertible” car seat that may be oriented in a rear-facing position and then “converted” to a front-facing position. Some convertible car seats may even convert into a booster seat for children weighing up to 100 pounds. Typically the convertible car seats are strapped into the car using the car seat-belt, or are anchored to the car frame directly using a LATCH (Lower anchors and Tethers for children) system. All car seats offer a harness for strapping the child into the seat. The usual harness is a five-point safety harness. The car seats tend to be formed from injection molded plastic, typically at least 5 mm (0.2 in) thick, and the seats (with base in the case of the infant seats) typically weigh 7 kgs (15.4 lbs) or more.
This summary is provided to introduce a selection of concepts that are further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.
According to one aspect of the disclosure, a vehicle seat includes a vehicle seat frame configured to connect directly to a chassis of a vehicle. The seat frame includes a back portion and a seat bottom portion extending at an angle with respect to the back portion. The seat bottom portion includes connectors that are configured for removably connecting to corresponding connection points of a car seat, such as an infant safety seat. The seat also includes a cover that is configured to connect to the frame. The cover includes at least one portion, which, in a first configuration, covers and conceals the connectors, and in a second configuration, exposes the connectors. At least one portion of the cover is partially or wholly removable to expose the connectors of the frame so that they can be used to connect to a car seat.
In one embodiment, the portion of the cover that conceals the connectors is separable from the cover. In at least one other embodiment, the portion of the cover that conceals the connectors is partially connected to the cover and is configured to fold over onto the cover to expose a corresponding connector.
According to one embodiment, the vehicle seat includes a cushion material, such as foam, disposed between an outer surface of the cover and the seat frame.
According to aspects of the vehicle seat, the vehicle frame may include a car seat base, which can be concealed in a first configuration when not in use, and exposed in a second configuration when needed to connect a car seat, such as an infant child car seat. Owing to this feature, a user need not install a separate car seat base on top of the vehicle seat cushions or remove and store such a base when no longer needed. Therefore, use of a car seat can be greatly simplified and installation can be improved.
The frame 600 may be formed of metal, such as aluminum. Of course, in other embodiments, the frame may be formed of other metals, such as titanium and steel, or non-metals, such as carbon fiber and plastic. Also, the horizontal and vertical portions 604 and 603 may be hollow or may be solid. For example, in one embodiment, the horizontal and vertical portions 604 and 603 are formed of tubular aluminum having a wall thickness of about 2 mm and an outer diameter of about 31.75 mm. It should be appreciated that for purposes herein, the term “tubular” does not require that a cross-section be round, as the tubular element may take any of many shapes.
The horizontal portion 604 extends from a front 611 to a back (mar) 606. The horizontal portion 604 has a cross bar 605 at or near the rear 606 of the horizontal portion 604. A pair of connectors 607, such as mini-connectors, extends from the cross bar 605. The connectors 607 are free to rotate relative to the cross bar 605. The connectors 607 are constructed to removably couple to anchors 700c (e.g., LATCH anchors) of the vehicle seat 700, which are located in the bight of the seat 700. In one embodiment, the vertical and horizontal portions 603 and 604, and cross bar 605 are formed of a metal, such as aluminum, and may be solid or tubular in form. The width between the connectors 607 is about the same as the width of the horizontal portion 604. In one embodiment, for example, the width between the connectors 607 may be about the standard width of vehicle anchors (e.g., LATCH anchors) of the vehicle seat, which is about 11 inches. Such dimensions are merely exemplary and are not intended to be limiting.
The horizontal portion 604 has a pair of hooks 602 and a latch mechanism 601, which is at or near the front of the horizontal portion 604. The hooks 602 are configured to hook to a corresponding first rod 120k (
The vehicle seat 700 includes a seatback portion 700a, a seat bottom portion 700b, and a seat frame 700c to which the seatback portion and seat bottom portion are secured. The seat frame 700c includes structural members that connect directly to the chassis or frame 800 of the vehicle. The frame 700c provides rigid support for the seatback portion 700a and seat bottom portion 700b, which may include padded upholstery and fabric, leather, or vinyl coverings. The seatback portion 700a may be pivotally adjustable with respect to the seat bottom portion 700b about axis A-A to permit the seat back portion 700a to recline back and forth and/or fold flat onto the seat bottom portion 700b.
The seat upholstery cover 701 has a seat bottom portion 701b that covers the horizontal portion 604′ of the frame 600′. Also, the seat upholstery cover 701 has a seat back portion 701a that covers the vertical portion 603′ of the frame 600′. While shown in
The horizontal portion 604′ of the frame 600′ is connected to the vehicle chassis 800 via frame members 702 and 703 at the front 611′ of the horizontal portion 604′, and via frame members 704 and 705 at the rear 606′ of the horizontal portion 604′. The vertical portion 603′ of the frame 600′ is connected to frame members 706 and 707 at lower ends 706b and 707b thereof and an intermediate spaced locations 706a and 707a above the lower ends of the frame members 706 and 707. The vertical portion 603′ may also or alternatively be connected to the frame members 706 and 707 at the upper end 609′ of the vertical portion 603′. The lower ends 706b and 707b of the frame members 706 and 707 are pivotally connected to the rear 606′ of the horizontal portion 604′ of the frame 600′. This pivotal configuration permits the vertical portion 603′, the seatback portion 700a′, and the seatback portion 701a of the cover 701 to fold together relative to the horizontal portion 604′, the seat bottom portion 700b′, and the seat bottom portion 701b of the cover 701. The pivotal connection between the frame members 706, 707, and the horizontal portion 604′ may be locked into one or more relative angular positions with a suitable locking mechanism (not shown) that will retain the locked position even in the event of severe forces and torque that may be transferred to the mechanism during a vehicle accident. Thus, once the locking mechanism is locked, the horizontal portion 604′ and the vertical portion 603′ of the frame 600′ may effectively be considered structurally unitary.
The seat bottom portion 701b of the cover 701 may include a removable panel 701c that is directly above the horizontal portion 604 of the frame 600. The panel 701c is configured to be moved to expose the connections of the horizontal portion 604 of the frame so that a car seat (e.g., car seat 10) can be connected to the frame 600. The panel 701c may be partially or wholly removable from the rest of the seat bottom portion 701b. For example, the panel 701c may be permanently or removably connected along its rear edge to the seat back portion 701a so that panel can be rotated upward about its rear edge toward the seat back portion 701a to uncover the horizontal portion 604 of the frame 600′. Also, instead of folding the panel 701c out of the way, the panel may be removed completely if the connection at the rear edge of the panel 701c is readily removable, such as if it includes hook and loop fasteners or snap connectors and the like.
It will be appreciated that in at least one embodiment, the vertical portion 603′ of the frame 600′ is omitted from the frame 600′, such that only the horizontal portion 604′ is connected to the vehicle seat 700′. Thus, in this embodiment, only the horizontal portion 604′ of the frame 600′ is secured to the vehicle chassis 800 via the seat bottom portion 700b′ and frame members 702 and 703 at the front 611′ of the horizontal portion 604′, and via frame members 704 and 705 at the rear 606′ of the horizontal portion 604′. This arrangement can further simplify construction of the vehicle seat 700′. Moreover, in at least one other embodiment, in addition to omitting the vertical portion 603′ of the frame 600′, the outer u-shaped frame member of the horizontal portion 604′ may be omitted so that only the pair of hooks 602′ and the latch mechanism 601′ of horizontal portion 604′ are fixed to bottom seat portion 700b′ of the vehicle seat frame 700c′.
In one embodiment, the seat back portion 701a of the cover 701 that covers the vertical portion 603′ may be removable or have a panelized portion (e.g., a lower portion) that can be removed. For example, vehicle seatback cushions may be about three to five inches thick. Therefore, by removing the seat back portion 701a, additional space (volume) can be freed up to accommodate the car seat and its occupant. For example, the additional space freed up by removing the seat back portion 701a can increase the legroom for rear-facing car seat occupants. Also, the additional space may be used to move the locations of the hooks 602 and latch mechanism 601 rearward, which can permit a car seat to be connected to the seat 700′ at a position spaced further away from the seatbacks (not shown) of vehicle seats (not shown) immediately forward of the seat 700′. This may allow for the installation of a larger car seat in smaller vehicles that might not otherwise accommodate the larger car seat if the additional space were not available. Also, increasing the spacing between a connected car seat and the seatbacks (not shown) of vehicle seats (not shown) immediately in front of the seat 700′ may aid in reducing the likelihood of the car seat and/or its occupant from contacting those seatbacks during a collision or during fore and aft adjustment of those seatbacks. This may be more relevant in vehicles having passenger compartments with limited legroom.
The frame 600″ has at least one female socket 1201 that is configured to receive a male projection 1202 (
Moreover, in one embodiment, only a single socket 1201 may be provided with a keyed feature to ensure alignment of the seat 10 with the frame 600″ in one corresponding direction. For example, as shown in
Prior to a connection process of connecting seat 10′ to the frame 600″, a user would uncover the sockets 1201a to 1201e by partially or fully removing the panel 701c′. During a connection process of the car seat 10′ to the frame 600″, a user places the car seat 10′ over the frame 600″ with the male projections 1202 extending downwardly facing the sockets 1201 and places the seat 10′ on the frame 600″ preferably in the vicinity of the sockets 1201. If the male projections 1202 do not initially align with the sockets 1201, the user can slide the car seat 10′ front to back and/or left to right relative to the frame 600″ until the projections 1202 align with the female sockets 1201. When the projections 1202 and the female sockets 1201 are aligned, the user can push the seat 10′ further downward into the frame to move the latch 1205 to the side of the opening of the socket 1201 and into an open position to clear the annular flange 1207 of the male projection 1202. Once the male projection 1202 is fully seated in the female socket 1201c, the latch 1205 automatically moves to the side over the upper flange 1207 of the male projection 1202, thereby locking the projection 1202 in the socket 1201c. The female socket 1201c can be unlocked from the male projection 1202 by displacing the latch 1205 to clear of the annular flange 1207 of the projection 1202, such as using a handle 1208 (
In an embodiment in which the frame 600″ is incorporated into the frame 700c′ the panel 701c may be alternately configured to have plug portions 1301a-1301e, as shown in
In an alternate embodiment, not shown, the plugs 1301a-1301e are not removable from the seat panel 701c, but instead are compressible and may be pushed down into the sockets 1201a-1201e by pushing on the plugs with the projections 1202. A user wishing to connect the car seat 10′ to the vehicle seat 700′ can align the projections 1202 of the seat with the locations of the plugs 1301a-1301e and push the seat 10′ down to compress the plugs into the sockets 1201a-1201e, which may be configured with sufficient depth to receive and accommodate the compressed plugs when the projections 1202 are fully connected in the sockets 1201a-1201e. Also, the plugs 1301a-1301e may be spring biased in the sockets 1201a-1201e to automatically rise upward to their original uncompressed level when the car seat 10 is disconnected from the vehicle seat 700′. Preferably, in the uncompressed level, the plugs 1301a-130e are flush with the surface of the panel 701c.
Also, in one embodiment shown in
The car seat mounting arms 810 are configured to pivot between a deployed configuration and a retracted configuration. In the deployed configuration, the arms extend above the bottom portion 700c″b and in the retracted configuration, the arms extend flush with or below the bottom portion 700c″b. In one embodiment, in the deployed configuration, the mounting arms 810 extend at an angle of about 90 degrees with respect to a plane of the bottom portion 700c″b. The mounting arms 810 are configured to be locked in the deployed configuration by a latch 822 (

When a user wishes to connect a car seat to seat 700″ (
There have been described and illustrated herein several embodiments of a vehicle seat and frame with integrated car seat mounting arrangements. While particular embodiments of the invention have been described, it is not intended that the invention be limited thereto, as it is intended that the invention be as broad in scope as the art will allow and that the specification be read likewise. Thus, while mounting arrangements and patters have been shown and described for concealment when not in use for connection to a car seat, it will be appreciated that other mounting arrangements may be used depending on the corresponding connection arrangement of the car seat. It will therefore be appreciated by those skilled in the art that yet other modifications could be made to the provided invention without deviating from its spirit and scope as claimed.
