Abstract
Abstract An improved restraint apparatus for use on an infant vehicle seat to reduce head and neck injury in infants. The improved restraint apparatus comprises a shell and padded lining shaped to partially enclose an infant when the restraint apparatus is attached to the infant vehicle seat. A first envelope of support is formed in an upper portion of the shell and padded lining to receive and support an infant head, and the first envelope of support provides a support against head movement. A second envelope of support is formed in a lower portion of the shell and padded lining and provides a support against torso movement comparable to the support against head movement. This produces a unified restraint system between the head and torso when the restraint apparatus is attached to the infant vehicle seat. The padded lining has soft glove like pockets that are shaped to receive, support and restrain an infant head and torso. The lining is removable for lining replacement to fit different head and torso sizes. The lining also includes distinct areas of different density in the padding to better absorb energy generated by an impact. The areas of different density in the padding apply a gradual increase in resistance against the head and torso as they are forced against the padded lining. The improved restraint further includes adjustment for fitting the restraint apparatus to different infant length sizes.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
213 words
A restraint apparatus for use with an infant vehicle seat to reduce injury by applying a unified restraint against the head and torso of an infant riding in the seat, the restraint apparatus comprising: a) a shell having a padded lining and a fastening means to attach said restraint apparatus to the infant vehicle seat; b) a first envelope of support formed in an upper portion of said shell and padded lining, said first envelope of support shaped to receive and restrain an infant head, said first envelope of support providing a restraint against head movement; and c) a second envelope of support formed in a lower portion of said shell and padded lining, said second envelope of support shaped to receive and restrain an infant torso, said second envelope of support providing a restraint against torso movement comparable to said restraint against head movement provided by said first envelope of support, said first envelope of support and said second envelope of support producing a unified restraint against head and torso movement when said restraint apparatus is attached to the infant vehicle seat wherein said shell equalizes relative acceleration between the head and the torso of the infant thereby causing the head and torso to uniformly react to a sudden change in force.
Claim 2
Dependent Claim
213 words
A restraint apparatus for use with an infant vehicle seat to reduce injury by applying a unified restraint against the head and torso of an infant riding in the seat, the restraint apparatus comprising: a) a shell having a padded lining and a fastening means to attach said restraint apparatus to the infant vehicle seat; b) a first envelope of support formed in an upper portion of said shell and padded lining, said first envelope of support shaped to receive and restrain an infant head, said first envelope of support providing a restraint against head movement; and c) a second envelope of support formed in a lower portion of said shell and padded lining, said second envelope of support shaped to receive and restrain an infant torso, said second envelope of support providing a restraint against torso movement comparable to said restraint against head movement provided by said first envelope of support, said first envelope of support and said second envelope of support producing a unified restraint against head and torso movement when said restraint apparatus is attached to the infant vehicle seat wherein said shell equalizes relative acceleration between the head and the torso of the infant thereby causing the head and torso to uniformly react to a sudden change in force.
Claim 3
Dependent Claim
89 words
The apparatus recited in claim 1 wherein: a) said first envelope of support provides a restraint against longitudinal and transverse head movement; and b) said second envelope of support provides a restraint against longitudinal and transverse torso movement comparable to said restraint against longitudinal and transverse head movement provided by said first envelope of support, said first envelope of support and said second envelope of support producing a unified restraint against longitudinal and transverse head and torso movement when said restraint apparatus is attached to the infant vehicle seat.
Claim 4
Dependent Claim
35 words
The apparatus recited in claim 1 wherein said unified restraint prevents a difference in relative acceleration between the head and torso of the infant when said restraint apparatus is attached to the infant vehicle seat.
Claim 5
Dependent Claim
54 words
The apparatus recited in claim 1 wherein: a) said first envelope of support includes a face opening extending through the shell and the padded lining of said restraint apparatus; and b) said second envelope of support includes at least one arm opening extending through said shell and said padded lining of said restraining apparatus.
Claim 6
Dependent Claim
32 words
The apparatus recited in claim 1 wherein said fastening means is positioned to removably attach said restraint apparatus to the infant vehicle seat at a location fitting a selected infant length size.
Claim 7
Dependent Claim
64 words
The invention recited in claim 5 wherein said fastening means comprises: a) a plurality of spaced apart fasteners positioned along the infant vehicle seat at locations corresponding to different infant length sizes; and b) fasteners extending from said restraint apparatus for removable attachment to any selected said spaced apart fasteners to removably attach said restraint apparatus at a location fitting a selected infant size.
Claim 8
Dependent Claim
22 words
The apparatus recited in claim 6 wherein said plurality of spaced apart fasteners include at least two locations fitting infant length sizes.
Claim 9
Dependent Claim
27 words
The apparatus recited in claim 5 wherein said fastening means includes at least one adjustable strap to removably attach said restraint apparatus to the infant vehicle seat.
Claim 10
Dependent Claim
50 words
The apparatus recited in claim 1 wherein: a) said first envelope of support includes a padded lining portion having a first pocket shaped to receive an infant head; and b) said second envelope of support included a padded lining portion having a second pocket shaped to receive an infant torso.
Claim 11
Dependent Claim
17 words
The apparatus recited in claim 9 wherein said padded lining includes padding having areas of different density.
Claim 12
Dependent Claim
16 words
The apparatus recited in claim 10 wherein said padding has the greatest density adjacent said shell.
Claim 13
Dependent Claim
20 words
The apparatus recited in claim 10 wherein said padding is least dense adjacent said first pocket and said second pocket.
Claim 14
Dependent Claim
28 words
The apparatus recited in claim 9 wherein said first pocket and said second pocket are shaped to fit the head and torso for a selected infant weight size.
Claim 15
Dependent Claim
