Abstract

A rear floor arrangement structure for a vehicle is provided. The rear floor arrangement structure includes a bottom part and a cross part that extends in a width direction of a vehicle body from one side of the bottom part. Additionally, a collision dispersion member is disposed at the bottom part and the cross part and the collision dispersion member extends along a collision direction of the vehicle body.

First claim

What is claimed is:

1 . A rear floor arrangement structure for a vehicle, comprising:
a bottom part; a cross part that extends in a width direction of a vehicle body from one side of the bottom part; and a collision dispersion member disposed at the bottom part and the cross part, wherein the collision dispersion member extends along a collision direction of the vehicle body, and wherein the collision dispersion member is formed of a composite material in which a plurality of fibers and a resin are combined.

2 . The rear floor arrangement structure for a vehicle according to claim 1 , wherein the collision dispersion member has at least one fiber layer in which a plurality of fibers are arranged in an orthogonal direction to the collision direction.

3 . The rear floor arrangement structure for a vehicle according to claim 1 , wherein the collision dispersion member includes at least one first fiber layer in which the plurality of fibers are arranged to be orthogonal to the collision direction and at least one second fiber layer in which the plurality of fibers is arranged in parallel with the collision direction.

4 . A rear floor arrangement structure for a vehicle, comprising:
a bottom part; a pair of side parts disposed at both sides of the bottom part; a cross part that extends by crossing the pair of side parts; and a collision dispersion part disposed at the bottom part and the cross part, wherein the collision dispersion part includes a plurality of collision dispersion members disposed at the bottom part and the cross part to be spaced part from each other along a width direction of a vehicle body.

5 . The rear floor arrangement structure for a vehicle according to claim 4 , wherein the collision dispersion member includes a first dispersion member disposed at the bottom part and a second dispersion member disposed at the cross member.

6 . The rear floor arrangement structure for a vehicle according to claim 5 , wherein the first dispersion member is disposed at the bottom part to extend along a length direction of the vehicle body.

7 . The rear floor arrangement structure for a vehicle according to claim 6 , wherein an inside of the first dispersion member includes a hollow part that extends along a length direction of the first dispersion member.

8 . The rear floor arrangement structure for a vehicle according to claim 7 , wherein both ends of the hollow part are closed.

9 . The rear floor arrangement structure for a vehicle according to claim 7 , wherein both ends of the hollow part are open.

10 . The rear floor arrangement for a vehicle according to claim 5 , wherein the second dispersion member is bent to correspond to an outer surface of the cross part.

11 . The rear floor arrangement structure for a vehicle according to claim 5 , wherein a reinforcement member is interposed between the first dispersion members and an inside of the reinforcement member includes a hollow part.

12 . The rear floor arrangement structure for a vehicle according to claim 11 , wherein the collision dispersion member and the reinforcement member are formed of a composite material in which a fiber and a resin are combined.

13 . The rear floor arrangement structure for a vehicle according to claim 4 , wherein the bottom part, the cross part, and the side part are formed in an integral structure.
