Abstract

An embodiment vehicle load distribution system includes a dash crossmember, a pair of front side members extending from the dash crossmember toward a front of a vehicle, and a pair of rear lower members extending from the dash crossmember toward a rear of the vehicle, wherein a front end of each rear lower member is aligned with a rear end of a corresponding front side member.

First claim

What is claimed is:

1. A load distribution system for a vehicle, the load distribution system comprising:
a dash crossmember;
a pair of front side members extending from the dash crossmember toward a front of the vehicle; and
a pair of rear lower members extending from the dash crossmember toward a rear of the vehicle, wherein a front end of each rear lower member is aligned with a rear end of a corresponding front side member,
wherein each front side member has an opening provided in the rear end thereof, and
wherein the dash crossmember is fitted and joined to the opening of the corresponding front side member.

2. The load distribution system according to claim 1 , wherein the opening of the front side member comprises a top engaging portion joined to a top surface of the dash crossmember, and a front engaging portion joined to a front surface of the dash crossmember.

3. The load distribution system according to claim 1 , wherein:
each rear lower member comprises a front engaging portion provided on the front end thereof; and
the front engaging portion is joined to a rear surface of the dash crossmember.

4. The load distribution system according to claim 3 , wherein:
the rear lower member further comprises a bracket integrally connected to the front end thereof; and
the bracket comprises a bottom engaging portion joined to a bottom surface of the dash crossmember.

5. A vehicle load distribution system comprising:
a dash crossmember;
a pair of front side members extending from the dash crossmember toward a front of a vehicle;
a pair of rear lower members extending from the dash crossmember toward a rear of the vehicle, wherein a front end of each rear lower member is aligned with a rear end of a corresponding front side member; and
a front crossmember located behind the dash crossmember in a longitudinal direction of the vehicle, wherein the pair of rear lower members connects the dash crossmember and the front crossmember in the longitudinal direction of the vehicle,
wherein each rear lower member has an opening provided in a rear end thereof, and
wherein the front crossmember is fitted and joined to the opening of a corresponding rear lower member.

6. The vehicle load distribution system according to claim 5 , wherein each opening of each rear lower member comprises a top engaging portion joined to a top surface of the front crossmember, a front engaging portion joined to a front surface of the front crossmember, and a bottom engaging portion joined to a bottom surface of the front crossmember.

7. The vehicle load distribution system according to claim 5 , further comprising:
a seat crossmember located behind the front crossmember in the longitudinal direction of the vehicle; and
a central longitudinal member connecting the dash crossmember and the seat crossmember, wherein the central longitudinal member extends along a central longitudinal axis of the vehicle.

8. The vehicle load distribution system according to claim 7 , wherein:
the central longitudinal member has a front opening provided in a front end thereof; and
the dash crossmember is fitted and joined to the front opening of the central longitudinal member.

9. The vehicle load distribution system according to claim 8 , wherein the front opening comprises a front engaging portion joined to a rear surface of the dash crossmember, and a bottom engaging portion joined to a bottom surface of the dash crossmember.

10. The vehicle load distribution system according to claim 7 , wherein:
the central longitudinal member has a rear opening provided in a rear end thereof; and
the seat crossmember is fitted and joined to the rear opening of the central longitudinal member.

11. The vehicle load distribution system according to claim 10 , wherein the rear opening comprises a top engaging portion joined to a top surface of the seat crossmember, a rear engaging portion joined to a front surface of the seat crossmember, and a bottom engaging portion joined to a bottom surface of the seat crossmember.

12. The vehicle load distribution system according to claim 7 , wherein:
the front crossmember has a central opening provided in a central portion thereof; and
the central longitudinal member is fitted and joined to the central opening of the front crossmember.

13. The vehicle load distribution system according to claim 12 , wherein the central opening comprises a bottom engaging portion joined to a bottom surface of the central longitudinal member, a first side engaging portion joined to a first side surface of the central longitudinal member, and a second side engaging portion joined to a second side surface of the central longitudinal member.

14. The vehicle load distribution system according to claim 7 , wherein the front crossmember, the rear lower member, and the seat crossmember each comprise a high-tensile strength steel plate.

15. The vehicle load distribution system according to claim 7 , wherein the front side member, the dash crossmember, and the central longitudinal member each comprise a mass-produced steel pipe.

16. The vehicle load distribution system according to claim 5 , wherein:
the front crossmember has a pair of side openings provided in both end portions thereof, respectively; and
each side sill is fitted and joined to a corresponding side opening of the front crossmember.

17. The vehicle load distribution system according to claim 16 , wherein each side opening comprises a side engaging portion joined to an inboard side surface of the side sill and a bottom engaging portion joined to a bottom surface of the side sill.

18. A load distribution system for a vehicle, the load distribution system comprising:
a dash crossmember;
a pair of front side members extending from the dash crossmember toward a front of the vehicle; and
a pair of rear lower members extending from the dash crossmember toward a rear of the vehicle, wherein a front end of each rear lower member is aligned with a rear end of a corresponding front side member,
wherein each rear lower member comprises a front engaging portion provided on the front end thereof, and
wherein the front engaging portion is joined to a rear surface of the dash crossmember.

19. The load distribution system according to claim 18 ,
wherein the rear lower member further comprises a bracket integrally connected to the front end thereof, and
wherein the bracket comprises a bottom engaging portion joined to a bottom surface of the dash crossmember.

20. The load distribution system according to claim 18 , further comprising:
a front crossmember located behind the dash crossmember in a longitudinal direction of the vehicle;
a seat crossmember located behind the front crossmember in the longitudinal direction of the vehicle; and
a central longitudinal member connecting the dash crossmember and the seat crossmember,
wherein the central longitudinal member extends along a central longitudinal axis of the vehicle, and
wherein the central longitudinal member has a front opening provided in a front end thereof, the dash crossmember being fitted and joined to the front opening of the central longitudinal member, or
wherein the central longitudinal member has a rear opening provided in a rear end thereof, the seat crossmember being fitted and joined to the rear opening of the central longitudinal member.
