Abstract

A bumper stiffener apparatus for a vehicle may include an upper member connected to a radiator grill, a lower member connected to a bumper below the upper member, a support bar connecting the upper member and the lower member, a hinge mechanism connected to the support bar, and a guide bracket fixed to a back beam arranged on a rear of the lower member to be connected to the hinge mechanism and in which a guide passage is formed for guiding an upward movement of the hinge mechanism when the lower member moves rearward.

First claim

What is claimed is:

1. A bumper stiffener apparatus for a vehicle comprising:
an upper member connected to a radiator grill;
a lower member connected to a bumper below the upper member;
a support bar connecting the upper member and the lower member;
a hinge mechanism fixed to the support bar; and
a guide bracket fixed to a back beam arranged on a rear of the lower member and to the hinge mechanism,
wherein the guide bracket includes a guide passage and the hinge mechanism is engaged to the guide passage and movable along the guide passage, and
wherein the guide passage guides an upward movement of the hinge mechanism along the guide passage when the lower member moves rearward.

2. The bumper stiffener apparatus for the vehicle of claim 1 , wherein the upper member and the lower member are arranged in leftward and rightward directions of the vehicle body in parallel.

3. The bumper stiffener apparatus for the vehicle of claim 1 , wherein support bars are arranged on both ends of the upper member and the lower member, respectively.

4. The bumper stiffener apparatus for the vehicle of claim 1 , wherein the hinge mechanism is disposed at a lower end of the support bar and over the lower member, and connected to the support bar, and guide brackets are arranged on both left and right ends of the back beam to be connected to hinge mechanisms, respectively.

5. The bumper stiffener apparatus for the vehicle of claim 1 , wherein the hinge mechanism comprises:
a hinge bracket fixed to the support bar and a holder portion of the hinge bracket protruded toward the back beam; and
a hinge pin inserted into the holder portion and the guide passage and moving along the guide passage when the lower member moves rearward.

6. The bumper stiffener apparatus for the vehicle of claim 5 , wherein the holder portion and the hinge pin are integrally connected or the hinge pin is arranged to be rotated within the holder portion.

7. The bumper stiffener apparatus for the vehicle of claim 5 , wherein the guide passage is formed to be a path through which the hinge pin moves rear-upward when the lower member moves rearward.

8. The bumper stiffener apparatus for the vehicle of claim 7 , wherein the guide passage further comprises an extended-passage extended rearward at an upper end of the guide passage and the hinge pin moves up to the extended passage to be fixed to the extended passage when the lower member moves rearward.

9. The bumper stiffener apparatus for the vehicle of claim 5 , further comprising a stopper arranged between the hinge bracket and the hinge pin and inserted into the guide passage when the hinge pin moves upward along the guide passage to support the hinge pin to prevent dropping of the hinge pin.

10. The bumper stiffener apparatus for the vehicle of claim 9 , wherein the stopper is configured such that a bottom surface of the stopper in contact with a bottom of the guide passage, a support surface in contact with the hinge bracket and an inclined surface on which the hinge pin is seated are consecutively connected to form an outline, and the inclined surface is inclined upward from an end of the inclined surface that is in contact with the hinge pin to another end of the inclined surface that is in contact with the support surface.
