Patent Application
20140015301
One or more aspects relate generally to restraint systems that employ webbing and, more particularly, to accessories for use in such systems.
Restraint systems, such as those involving harnessing, are used in a range of applications including sporting goods, automotive safety and military equipment. For example, a variety of child restraint devices have been developed for use in automobiles and child conveyance devices, such as strollers and infant carriers. These restraint devices, often referred to as infant or child seats, adequately restrain a small child or infant by way of a harness connected to and in cooperation with a seat portion of the device. Webbing is a versatile component of many restraint systems. Webbing is typically made of a light and strong fabric that is woven as a flat strip to engage with system hardware, such as fasteners, ladder locks, buckles and other fittings to facilitate restraint.

One or more embodiments relate generally to securing mechanisms, such as restraint systems or harnesses that employ webbing. Certain embodiments relate specifically to securing mechanisms of child restraint devices. Other embodiments may find use in other applications including sporting goods, automotive safety and military equipment. Accessories in accordance with one or more embodiments may increase security and ease of operation of restraint systems. In some embodiments, an accessory may beneficially facilitate adjustment of webbing. In at least some embodiments, an accessory may prevent unintended shifting of the webbing. Movement of the accessory itself may also be hampered. In some embodiments, a free portion of webbing may be secured for safety and convenience.
Conventional child seats generally include a main body that has a child support area disposed on its upper or interior surface to receive a child or infant in a sitting position. The child support area of the main body may include a lower seat portion upon which a child may sit, and an upper back portion for supporting the back of the child.
Child seats are generally equipped with a harness system to restrain a child within the device. The harness system may include multiple sections of webbing that are joined by connecting mechanisms. A harness configuration may comprise a “five point” harness. A five point harness may include webbing sections that form a lap belt portion, a crotch restraint portion, and two shoulder restraint portions. In a five point harness, the belt portion generally extends from, or at the sides of, the main body of the child seat to restrain the child about its waist. A crotch restraint portion is generally positioned between the child's legs and extends from the base of the child seat to the lap belt portion. The shoulder restraint portions generally extend from the upper back portion of the seat body over the child's shoulders and restrain the child about the chest. These portions may be collectively engaged by a buckle mechanism that positions about the child's midsection. Some portions of webbing may be permanently secured in the buckle mechanism. Other portions of webbing may terminate in hardware, such as latch plates, that may be releasably secured in the buckle. When the latch plates are not engaged with the buckle mechanism, the attached portions of webbing are freely movable and the harness is not secured. The harness may be secured by inserting the latch plates into the buckle, thus engaging the lap belt portion, crotch restraint, and shoulder harness portions to form a network of webbing capable of adequately restraining the child.
Once a child has been placed in the seat and the harness system is engaged, it is often necessary to tighten the harness. Likewise, to disengage the harness and remove a child from the seat, it is often necessary to first loosen the system. Tightening and loosening may be accomplished by adjusting the relative lengths of portions of the webbing. Portions of the webbing are commonly threaded through ladder locks that allow an operator to shorten or lengthen the portions that restrain the child. To tighten the webbing, the operator pulls on a free end of the webbing. This causes more of the webbing to be thread through the ladder lock and shortens the length of webbing between the main body of the seat and the buckle, causing the harness to tighten about the child. To loosen the webbing, the operator causes the ladder lock to lengthen the portion of webbing between the body and buckle, often by pulling the ladder lock itself or by manipulating a portion of the free webbing back through the ladder lock and towards the seat body.
The free portion of webbing which allows an operator to manipulate a harness system presents an obstacle to safe child restraint. Because a portion of webbing remains free and unsecured from the harness or main body of the child seat, it can be manipulated by an infant or child secured in the seat. Infants and children restrained by webbing harnesses thus may play with, and undesirably manipulate, the free end of webbing. This manipulation can lead to dangerous over-tightening or loosening of the harness. Webbing ends may collect dirt and bacteria and infants and young children may undesirably engage the webbing end with their mouth. Furthermore, the free end of webbing may fray or otherwise degrade over time due to frictional contact or other manipulation. Degradation of webbing may shorten the usable lifespan of a restraint device. These points are also of concern in other types of restraint systems and harnessing which involve webbing.
In accordance with one or more embodiments, a harness system may include webbing, at least one hardware component, such as a connecting mechanism, and at least one accessory. In accordance with one or more embodiments, an accessory for a child restraint system may advantageously receive a free portion of a webbing harness and secure it to another portion of the webbing harness. The accessory may be made of any material of adequate strength for the intended application and may be of any size and shape based upon the intended application. The accessory may thus be made of plastics, rubbers, metals, or other suitable materials. The accessory may be molded, injection molded, extruded, or otherwise formed in accordance with the selected material.
In accordance with one or more embodiments and referring to

In accordance with one or more embodiments and referring to
In one or more embodiments, an accessory for a restraint system may further include a mechanism, such as a locking mechanism, configured to interfere with movement of the accessory. When engaged, the mechanism may interfere with movement of the accessory along the portion of webbing to which it is secured. The mechanism may provide an additional safeguard against the inadvertent manipulation of webbing by a restrained infant or child. The mechanism may include a friction element or pressure element that, when engaged, exerts a force on the webbing to which the accessory structure is secured. The frictional element may thus provide a frictional force that slows or stops movement in relation to the webbing to which it is secured. When disengaged, the friction element does not exert substantial force on the webbing and thus the accessory can be moved freely.
Referring specifically to
One or more embodiments relate generally to an overall harness system. A harness system may be any system that operates to restrain a subject or object in a desired position. In accordance with
In accordance with one or more embodiments and referring to
Ladder lock 320 is further in communication with webbing 340. Webbing 340 has an upper portion, 340A, and a lower portion 340B. Upper webbing portion 340A is defined by the portion of webbing 340 that is thread, from bottom to top, through ladder lock 320. Webbing 340 could alternatively be thread from top to bottom. Bottom webbing portion 340B is webbing portion 340 that is not threaded through ladder lock 320. Bottom portion 340B may extend, as shown by dotted lines, and be fixed to a child seat to form a lap belt portion of a harness system. Webbing 340 is fixed in length. Upper portion 340A and bottom portion 340B may be shortened or lengthened via ladder lock 320. As one portion shortens, the other portion necessarily lengthens. Webbing 340B controls the length of the lap belt portion of harness system 400. As 340B shortens, the overall lap belt shortens in length and tightens about an occupant.
Harness system 400 may be tightened by causing more of bottom webbing portion 340B to be thread through ladder lock 320. This is commonly done when an operator applies force to webbing upper portion 340A in a direction that causes portion 340A to lengthen. The force exerted on webbing 340A causes bottom portion 340B to shorten, as more of webbing bottom portion 340B is thread upward through the ladder lock (thus becoming 340A). As 340B shortens, the length of the lap belt shortens and tightens about an occupant. The harness may be loosened by causing more of webbing 340A to be thread downward into the ladder lock and lengthen portion 340B.
Harness system 400 further includes accessory 300. Referring to
In accordance with one or more embodiments, fixing mechanism 350 allows accessory 300 to traverse along bottom webbing portion 340B. Thus, the fixing mechanism allows adjustment of the webbing harness by an operator even when the accessory is fixed to portion of the harness.
In accordance with one or more embodiments, accessory 300 may comprise a locking mechanism (not shown). A locking mechanism, when engaged, may interfere with movement of the accessory along webbing portion 340B. Thus when the locking mechanism is engaged, the ratio of webbing portion 340A to 340B cannot be as easily changed. The locking feature may further safeguard against any undesirable manipulation of the harness by an occupant.
Harness system 400 may be incorporated into a child seat to restrain a child.
Existing systems may be retrofitted by providing and implementing an accessory in accordance with one or more embodiments. Instructions may be provided to engage the accessory with webbing in accordance with one or more embodiments.
