Abstract
An improvement on a vehicle floor structure is provided which includes joint members each of which has a closed hollow structure and joins a rear extension of one of side sills, one end of a rear seat cross member, and a front end of one of rear side members. Each of the joint members is installed between one end of the rear seat cross member and one of the side sills and has a lower-rigidity region formed adjacent the end of the rear seat cross member for facilitating ease of a lateral collapse of a vehicle body in the lower-rigidity region upon occurrence of a side collision of the vehicle.
Claims21
A vehicle floor comprising:
- a front floor formed in extrusion, said front floor being so oriented that a direction of the extrusion is in parallel to a longitudinal direction of a vehicle;
- a rear floor joined to a rear end of said front floor;
- side sills disposed on sides of said front floor, each of said side sills extending in the longitudinal direction of the vehicle and having an extension projecting backward from said front floor;
- a rear seat cross member having a length extending in a width-wise direction of the vehicle, said rear seat cross member being disposed on a connection of said rear floor to said front floor extending in the width-wise direction of the vehicle;
- rear side members disposed on sides of said rear floor, extending in the longitudinal direction of the vehicle;
- pillars secured on said side sills above said rear seat cross member;
- and
- joint members each of which has a closed hollow structure and joins the extension of one of said side sills, one end of said rear seat cross member, and a front end of one of said rear side members, each of said joint members being installed between one end of said rear seat cross member and one of said side sills and having a lower-rigidity region formed adjacent the end of said rear seat cross member in the width-wise direction of the vehicle.
