Abstract
Abstract For the purpose of significantly reducing the steps for assemblage and accordingly the production cost of an impact absorbing vehicle body structure adapted to dampen out energy of an impact or collision by plastic deformation of deformable members, an assembly preliminarily built by at least one impact absorbing unit and at least one cross member carrying the impact absorbing unit is mounted as a whole on a mounting member which is preliminarily connected to a main body of the vehicle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
An impact absorbing body structure for a motor vehicle having a main body structure and a bumper, comprising: a mounting plate member secured to a lower rigid portion of said main body structure; a cross member adapted to be detachably fixed to said mounting plate member; and at least one pair of elongated deformable first units which are longitudinally contractable when subjected to an impact, said first units being firmly connected at one ends thereof to said cross member and being arranged in a parallel spaced relation and extending in the longitudinal direction of the motor vehicle so as to constitute a longitudinal end portion of a vehicle body structure, and said first units having the other ends connected to said bumper.
Claim 2
Dependent Claim
122 words
An impact absorbing body structure for a motor vehicle having a main body structure and a bumper, comprising: a mounting plate member secured to a lower rigid portion of said main body structure; a cross member adapted to be detachably fixed to said mounting plate member; and at least one pair of elongated deformable first units which are longitudinally contractable when subjected to an impact, said first units being firmly connected at one ends thereof to said cross member and being arranged in a parallel spaced relation and extending in the longitudinal direction of the motor vehicle so as to constitute a longitudinal end portion of a vehicle body structure, and said first units having the other ends connected to said bumper.
Claim 3
Dependent Claim
30 words
An impact absorbing body structure as claimed in claim 1, in which said cross member and said mounting plate member are detachably connected with each other in substantially male-female relationship.
Claim 4
Dependent Claim
56 words
An impact absorbing body structure as claimed in claim 2, in which said cross member is formed with a projection and said mounting plate member is formed with a recess which is positioned and configured to be in correspondence with said projection when the first cross member is to be combined with the mounting plate member.
Claim 5
Dependent Claim
41 words
An impact absorbing body structure as claimed in claim 3, in which said first cross member and said mounting plate member are rigidly connected to each other by at least one bolt which is screwed through the projection and the recess.
Claim 6
Dependent Claim
231 words
An impact absorbing body structure for a motor vehicle having a main body structure and a bumper, comprising: a mounting plate member secured to a rigid portion of said main body structure; a first cross member adapted to be detachably fixed to said mounting plate member; at least one pair of elongated deformable first units and at least one pair of elongated deformable second units which are longitudinally contractable when subjected to an impact, said first units being firmly connected at one ends thereof to a relatively lower portion of said first cross member, and said second units being firmly connected at one ends thereof to a relatively upper portion of said first cross member, both said first units and second units being arranged in a parallel spaced relation and extending in the longitudinal direction of the motor vehicle so as to constitute a box-shaped framework on a longitudinal end portion of a vehicle body structure; a second cross member having a lower portion supporting said first units and an upper portion connected to the other ends of said second units; and a pair of elongated members having one ends telescopically connected with the other ends of said first units respectively and the other ends connected with said bumper, said pair of elongated members being constructed to deform said first units upon receiving the impact force due to the vehicle collision.
Claim 7
Dependent Claim
231 words
