Abstract

In a motor vehicle having a body and a drive unit consisting of an engine and transmission provided with forwardly disposed support mounts secured forwardly thereof to the vehicle body, a drive unit rear end support assembly comprising a member mounted on the vehicle body providing a bearing surface and a support member rigidly secured to the drive unit, extending rearwardly therefrom and resting on the bearing surface.

Claims

1. In a motor vehicle having a body (1A) and a drive unit (1) consisting of an engine (3) and transmission (4) mounted thereon, a drive unit support assembly comprising:

a bearing (7) mounted on said body and a support member (5) extending from said drive unit, said support member extending rearwardly from said drive unit and into said bearing;

a cable grabbing means (14) secured to said support member, a cable reeving means (12,

     13) rigidly secured to said body, and a cable (15) secured at one end thereof to a steering column (16) said cable extending around said cable grabbing means and said cable reeving means, and thereafter secured to said body (1a) whereby upon a frontal collision of said vehicle and a corresponding rearward displacement of said drive unit, said cable will be drawn by said drive unit rearward displacement and will correspondingly displace said steering column longitudinally forwardly; and

means for adjustably mounting said cable grabbing means on said support member whereby said cable grabbing means is displaceable along said support member to accommodate drive units of differing sizes.

2. An assembly according to claim 1 wherein said support member is tubular.

3. An assembly according to claim 1 wherein said support member has a square cross-sectional configuration.

4. An assembly according to claim 1 including bracket means (8) rigidly secured to said body whereby upon said frontal collision and corresponding rearward displacement of said drive unit, a free end (11) of said support member contacts said bracket means.

5. An assembly according to claim 4 wherein said support member is deformable upon rearward displacement thereof and engagement with said bracket means for absorbing collision energy.

6. An assembly according to claim 5 wherein said support member is capable of deforming in a crimping manner in absorbing said collision energy.

7. An assembly according to claim 1 wherein said bearing (7) is a torque bearing and said support member is supported in said torque bearing.

8. An assembly according to claim 1 further comprising a second cable (18) secured at one end thereof to a passenger restraining belt (20), said second cable extending around said cable grabbing means and said cable reeving means whereby upon said frontal collision of said vehicle, said second cable will be drawn by said drive unit rearward displacement, resulting in the tightening of said passenger restraining belt.
