Description

Field of Invention

[0002] The invention pertains to padding material for seating structures. More particularly, the invention relates to removable seat padding designed for use with portable child automobile seats.

Background of the Invention

[0003] Laws in most states now mandate the use of child safety seats for infants and children under certain weight limits when riding in automobiles. While many designs for child safety seats have been developed, most if not all, provide only rudimentary padding for the developing bones and skeletal structures of infants and small children. As many children spend considerable time in these child safety seats the potential for discomfort, injury and even improper development of bones, muscles and skeletal structures is a very real problem.

[0004] Various devices have been developed to provide padding for repeated human contact with hard surfaces. U.S. Pat. No. 5,865,180 issued to Sigfrid discloses a pocket connected to a cover into which is introduced a removable pad and a second pocket designed to close over the pad and the first pocket.

[0005] U.S. Pat. No. 5,388,295 issued to Sarkozi, is directed to an adjustable seat and back support pad and mattress that is useful in a car, the pad can be assembled using Velcro, hook-and-loop and can be filled with an elastomer material such as solid or pelletized foam, fiber, cotton gauze, shredded cloth, air, water, gel, etc. This patent discloses an array of resilient, longitudinal, parallel support pads, hingedly attached together, that may be filled with gel. U.S. Pat. No. Re. 34,573, issued to Calvert is directed to a liquid filled bladder for relieving muscle fatigue, pressure sores, blistering, numbness, reduced blood circulation, and tissue damage of an assembly line worker, truck driver, hammer or jackhammer operator, etc. U.S. Pat. No. 4,471,538 issued to Pomeranz et al. is directed to one or more deformable sealed chambers containing a shock absorbing rheopexic fluid for use as shoe inserts, bed tops, horse saddles, bicycle saddles, gloves, or the like.

[0006] While other variations exist, the above-described designs for padding systems and structures are typical of those encountered in the prior art. It is an objective of the present invention to provide padding for a child's safety seat that will protect the user from the hard surfaces of the seat. It is a further objective to provide for padding that will conform to the body of the user. It is yet a further objective to provide a seat pad that may be easily secured to a variety of conventional safety seats. It is still a further objective to provide seat pads suitable for both infants and older children. Finally, it is objective of the invention to provide the above-described capabilities in an inexpensive and durable pad that includes a cover that is removable and washable.

[0007] While some of the objectives of the present invention are disclosed in the prior art, none of the inventions found include all of the requirements identified.
