Abstract
Abstract A vehicle body structure is disclosed which provides a strengthened support for a strut suspension and an increased rigidity of a vehicle body. The strut suspension is supported by a member attached to a box-girder structure extending longitudinally of the vehicle body and rigidly secured to any structural member, such as a front pillar, of the vehicle body. The box-girder structure may preferably be narrowed toward its foremost end so as to be collapsible when subjected to a forceful mechanical stress during collision of the motor vehicle. Arrangements may also be made so that the vehicle body structure can be assembled in a simplified manner.

Claim 1
Independent Claim
62 words
A vehicle body structure in a vehicle body having a strut suspension and a front pillar, comprising a box-girder structure disposed on the side of the vehicle body and extending generally longitudinally of the vehicle body, said box-girder structure rigidly secured at its rear end to said front pillar and having therein a portion receiving an upper portion of said strut suspension.
Claim 2
Dependent Claim
62 words
A vehicle body structure in a vehicle body having a strut suspension and a front pillar, comprising a box-girder structure disposed on the side of the vehicle body and extending generally longitudinally of the vehicle body, said box-girder structure rigidly secured at its rear end to said front pillar and having therein a portion receiving an upper portion of said strut suspension.
Claim 3
Dependent Claim
28 words
A vehicle body structure according to claim 1, in which said box-girder structure is narrowed toward its foremost end for collapsing when subjected to a rearward mechanical stress.
Claim 4
Dependent Claim
64 words
A vehicle body structure according to claim 1, in which said box-girder structure comprises a fore portion having therein a portion receiving the upper portion of said strut suspension and a rear portion formed integrally with said fore portion which extends generally rearwardly and obliquely to the longitudinal direction of the vehicle body and which is secured at its rear end to said pillar.
Claim 5
Dependent Claim
73 words
A vehicle body structure according to claim 1, in which said box-girder structure comprises an inner structural member having an upper end wall sidewise bent outwardly and an outer structural member having a lower end wall sidewise bent inwardly, said inner and outer structural members rigidly secured to each other at end edges of said upper and lower end walls of said inner and outer structural members, respectively thereby defining a box shape.
Claim 6
Dependent Claim
39 words
A vehicle body structure according to claim 4, in which each of said inner and outer structural members comprises a fore part extending forwardly and a rear part secured to said front pillar and welded to said fore part.
Claim 7
Dependent Claim
64 words
A vehicle body structure according to claim 5, in which said fore part of said inner structural member has means defining a recess formed in a rearmost portion of its upper end wall providing an access to a space defined by the fore and rear parts of said inner and outer structural members during welding operation for the assembling of said vehicle body structure.
Claim 8
Dependent Claim
45 words
A vehicle body structure according to claim 5, wherein one of the fore parts is longer than the other and the rear part to be welded to said one fore part is shorter than the rear part to be welded to the other fore part.
Claim 9
Dependent Claim
40 words
A vehicle body structure according to claim 5, comprising a dashboard forming part of said vehicle body and a connecting member attached to said dashboard defining a space therebetween and both welded to the fore part of said front pillar.
Claim 10
Dependent Claim
35 words
A vehicle body structure according to claim 8, further comprising a cowl top member having a rearmost end and a foremost end welded to both said dashboard and said connecting member to close said space.
Claim 11
Dependent Claim
32 words
A vehicle body strUcture according to claim 9, in which said cowl top member has a raised side edge welded to an upper end of the rear part of said front pillar.
Claim 12
Dependent Claim
24 words
A vehicle body structure according to claim 1, in which said front pillar includes a forward extension Which forms part of said box-girder structure.
Claim 13
Dependent Claim
48 words
In a vehicle body having a strut suspension and a front pillar; a box girder disposed on the side of said vehicle body and having one end portion rigidly secured to said front pillar and extending longitudinally therefrom and connected to an upper portion of said strut suspension.
Claim 14
Dependent Claim
48 words
In a vehicle body having a strut suspension and a front pillar; a box girder disposed on the side of said vehicle body and having one end portion rigidly secured to said front pillar and extending longitudinally therefrom and connected to an upper portion of said strut suspension.
Claim 15
Dependent Claim
21 words
In a vehicle body according to claim 12, wherein said box girder is disposed obliquely with respect to said vehicle body.
Claim 16
Dependent Claim
46 words
In a vehicle body according to claim 12, wherein the other end portion of said box girder has a narrower cross-section than the remaining portion to enable said box girder to collapse upon the application of a force in a direction towards said one end portion.
Claim 17
Dependent Claim
44 words
In a vehicle body according to claim 12, wherein said box girder comprises an inner member having an L-shaped cross-section, and an outer member having an L-shaped cross-section and rigidly secured to said inner member along the length thereof thereby defining a box-shaped cross-section.
Claim 18
Dependent Claim
44 words
In a vehicle body according to claim 15, wherein each of said inner and outer memebers comprises a fore piece, and a rear piece having one end portion rigidly connected to said front pillar and another end portion rigidly connected to said fore piece.
