Abstract

A horizontal impact member for use with a rear impact guard on a semi-trailer truck is disclosed. The horizontal impact member is connected to a standard rear impact guard by a hinge. This design is for use with a liftgate that is mounted to the rear of the semi-trailer truck. As the liftgate travels in a downwardly vertical direction it contacts the horizontal member which rotates along its hinge point. The addition of a roller to the horizontal member reduces the amount of wear upon the horizontal member and the liftgate.

Claims

1. An improved impact guard for a vehicle, the vehicle having a front, a rear, a liftgate mounted to the rear of the vehicle, the liftgate having a vertical member and a platform, the liftgate able to travel in an upwardly and downwardly vertical direction, the impact guard comprising:

a first and second horizontal impact member;

a mounting means to mount said impact guard to the rear of the vehicle,

a hinge means to hinge said second horizontal impact member to said first horizontal impact member; and

,

whereby the liftgate impacts said impact guard when traveling in a downwardly vertical direction causing said second horizontal impact member to rotate about said hinge means.

2. The improved impact guard as recited within claim 1, further comprising:

an impact-absorbing means, said impact-absorbing means mounted within said impact guard; and

,

whereby said liftgate impacts said impact-absorbing means of said impact guard.

3. The improved impact guard as recited within claim 1, wherein said impact-absorbing means further comprises a roller mounted within said second horizontal impact member.

4. The improved impact guard as recited within claim 1, wherein said hinge means is mounted below said first horizontal impact member.

5. The improved impact guard as recited within claim 1, wherein said hinge means is mounted between said first and said second horizontal impact member.

6. The improved impact guard as recited within claim 1, wherein said second horizontal impact member is rotatable greater than 90°

below said first horizontal impact member.

7. The improved impact guard as recited within claim 1, wherein said second horizontal impact member is rotatable less than 90°

below said first horizontal impact member.
