Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
A head rest having an energy-absorbing padding, particularly for vehicle seats, comprising a supporting frame structure disposed interiorly thereof having a rounded upper edge to provide a supporting surface, the interior frame structure being substantially non-deformable in response to impact forces, a deformable hollow shell member surrounding said frame structure and having a high capacity of energy absorption by deformation, a deformable rib structure disposed interiorly of said hollow shell and arranged to support said member in substantially spaced relation to said frame structure, and a thin, soft padding of upholstery material covering said head rest.
Claim 2
Dependent Claim
96 words
A head rest having an energy-absorbing padding, particularly for vehicle seats, comprising a supporting frame structure disposed interiorly thereof having a rounded upper edge to provide a supporting surface, the interior frame structure being substantially non-deformable in response to impact forces, a deformable hollow shell member surrounding said frame structure and having a high capacity of energy absorption by deformation, a deformable rib structure disposed interiorly of said hollow shell and arranged to support said member in substantially spaced relation to said frame structure, and a thin, soft padding of upholstery material covering said head rest.
Claim 3
Dependent Claim
52 words
A head rest according to claim 1, in which said frame structure has a pair of lateral supporting members and a band at the upper edge thereof, said band having a large area and being tensioned between said lateral members and supporting said deformable hollow shell member with the rib structure thereof.
Claim 4
Dependent Claim
25 words
A head rest according to claim 1, in which the surface of said interior structure supporting said rib structure is covered with damping hard-foam material.
Claim 5
Dependent Claim
39 words
A head rest according to claim 1, in which said deformable hollow shell member and said padding are provided with lateral ear members for supporting the head and extending forwardly within the area of possible contact with the head.
Claim 6
Dependent Claim
29 words
A head rest according to claim 4, in which said ear members extend from below the middle of the head portion to the rear part of the upper side.
Claim 7
Dependent Claim
29 words
A head rest according to claim 1, in which said deformable member, said rib structure and said padding extend on the rear side substantially below said supporting frame structure.
Claim 8
Dependent Claim
24 words
A head rest according to claim 1, in which said rib stRucture is formed as an integral part of said deformable hollow shell member.
Claim 9
Dependent Claim
27 words
A head rest according to claim 7, in which said deformable hollow shell member comprises sheet material having stiffening elements provided therein to form said rib structure.
Claim 10
Dependent Claim
20 words
A head rest according to claim 7, in which said deformable member comprises hard foam material forming a rib structure.
