Abstract
Abstract An improved vehicle door is provided which is resistant to impact at high deflection. Such a door is provided by incorporating within the door in a region most likely to be subject to impact, a plurality of horizontally extending resilient members supported generally adjacent opposing portions of the door frame. Beneficially, the resilient members are a composite material such as a hardened synthetic resin and a plurality of longitudinally extending resilient fibers such as fibers of glass.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
A vehicle member, the vehicle member comprising a supporting frame, the supporting frame enclosing therein a region of probable impact, and first and second frame portions generally oppositely disposed and having therebetween the region of the probable impact, at least one resilient deflectable generally bar shaped member having a major axis, the member being disposed between opposed frame portions and supported by and slidably affixed to said frame portions, the member being slidable in the direction of the major axis whereby an impact in the region of probable impact and deflection of the member, relatively little force is exerted which would serve to draw frame member portions together.
Claim 2
Dependent Claim
108 words
A vehicle member, the vehicle member comprising a supporting frame, the supporting frame enclosing therein a region of probable impact, and first and second frame portions generally oppositely disposed and having therebetween the region of the probable impact, at least one resilient deflectable generally bar shaped member having a major axis, the member being disposed between opposed frame portions and supported by and slidably affixed to said frame portions, the member being slidable in the direction of the major axis whereby an impact in the region of probable impact and deflection of the member, relatively little force is exerted which would serve to draw frame member portions together.
Claim 3
Dependent Claim
13 words
The vehicle member of claim 1 including a plurality of resilient deflectable members.
Claim 4
Dependent Claim
15 words
The vehicle member of claim 2 wherein the plurality of deflectable members are generally parallel.
Claim 5
Dependent Claim
12 words
The vehicle member of claim 1 where the member is a door.
Claim 6
Dependent Claim
18 words
The vehicle member of claim 4 wherein the door is a hollow door having resilient members disposed therein.
Claim 7
Dependent Claim
14 words
The member of claim 5 wherein the resilient deflectable member has a bar-shaped configuration.
Claim 8
Dependent Claim
23 words
The member of claim 6 wherein the bar-shaped member comprises a plurality of longitudinally extending generally parallel glass fibers in a resinous matrix.
Claim 9
Dependent Claim
18 words
The member of claim 1 wherein the resilient members are affixed in channel-shaped members to the frame portions.
Claim 10
Dependent Claim
19 words
The member of claim 8 wherein the resilient members are secured in the channels by a low strength adhesive.
Claim 11
Dependent Claim
124 words
A vehicle door, the vehicle door comprising a supporting frame, the supporting frame enclosing therein a region of probable impact, the frame having first and second portions generally oppositely disposed and having therebetween the region of probable impact, a plurality of resilient bar-shaped deflectable members, having major axes disposed between opposed frame portions and supported by said frame portions, the resilient members being disposed in generally parallel relationship to each other, each of the resilient members being generally axially slidably supported by the first and second frame portions and retained therein by a low strength adhesive whereby an impact in the region of probably impact and deflection of the members, relatively little force is exerted which would serve to draw frame member portions together.
Claim 12
Dependent Claim
124 words
A vehicle door, the vehicle door comprising a supporting frame, the supporting frame enclosing therein a region of probable impact, the frame having first and second portions generally oppositely disposed and having therebetween the region of probable impact, a plurality of resilient bar-shaped deflectable members, having major axes disposed between opposed frame portions and supported by said frame portions, the resilient members being disposed in generally parallel relationship to each other, each of the resilient members being generally axially slidably supported by the first and second frame portions and retained therein by a low strength adhesive whereby an impact in the region of probably impact and deflection of the members, relatively little force is exerted which would serve to draw frame member portions together.
Claim 13
Dependent Claim
79 words
A vehicle member, the vehicle member comprising a supporting frame, the supporting frame enclosing therein a region of probable impact, and first and second frame portions generally oppositely disposed and having therebetween the region of probable impact, at least one resilient deflectable member, the resilient member having at least first and second portions, the first and second portions, one telescoping within the other, the resilient deflectable member being disposed between opposed frame portions and supported by said frame portions.
Claim 14
Dependent Claim
79 words
A vehicle member, the vehicle member comprising a supporting frame, the supporting frame enclosing therein a region of probable impact, and first and second frame portions generally oppositely disposed and having therebetween the region of probable impact, at least one resilient deflectable member, the resilient member having at least first and second portions, the first and second portions, one telescoping within the other, the resilient deflectable member being disposed between opposed frame portions and supported by said frame portions.
