Abstract

A body for a passenger car has a body-in-white structure which is located behind a wheel well for a front wheel of the passenger car and which has a transverse member that extends on the outside of a longitudinal beam of the body-in-white structure in front of a front end wall of the body-in-white structure in the vehicle transverse direction. The transverse member has a catch element which is designed to catch a rim of the front wheel that has moved backwards in the vehicle longitudinal direction in the event of an accident and is turning in rearward towards the vehicle center. The body-in-white structure has an A-pillar located behind the catch element, a lateral sill located behind the catch element, and a support element which is located in the A-pillar and via which the catch element that has moved backwards in the event of an accident and, via the catch element, the rim that has moved backwards in the event of an accident, can be supported towards the rear on the lateral sill.

First claim

The invention claimed is:

1. A body for a passenger motor vehicle, comprising:
a shell structure which is arranged behind a wheel housing for a front wheel of the passenger motor vehicle, the shell structure comprising:
a transverse member that extends on an outer side of a longitudinal member of the shell structure in front of a front end wall of the shell structure in a transverse vehicle direction, wherein:
the transverse member has a catch element configured to catch a rim of the front wheel which is displaced backward in a longitudinal vehicle direction as a result of an accident, which rim turns inward in a backward direction toward a vehicle center;
an A-pillar is arranged behind the catch element in the longitudinal vehicle direction;
a lateral sill is arranged behind the catch element in the longitudinal vehicle direction;
a support element is arranged in the A-pillar via which the catch element, which is displaced backward in the longitudinal vehicle direction as a result of the rim being caught as a result of an accident, is supportable, and thereby the rim which is displaced backward in the longitudinal vehicle direction as a result of the accident is supportable on the lateral sill in a backward direction in the longitudinal vehicle direction; and
the transverse member comprises a front shell element and a rear shell element which are connected to one another to form a hollow space, wherein a reinforcing element is arranged in the hollow space and extends from the catch element in the transverse vehicle direction toward the vehicle center.

2. The body according to claim 1 , wherein
the support element is of wedge-shaped form and extends diagonally in a corner region which is formed by the lateral sill and the A-pillar.

3. The body according to claim 2 , wherein
the support element is supported in a downward direction in a vertical vehicle direction, directly on the lateral sill, and/or in a forward direction in the longitudinal vehicle direction directly on the A-pillar.

4. The body according to claim 2 , wherein
an upper side, which is directed upward in the vertical vehicle direction, of the support element extends from an upper front region to a lower rear region in the longitudinal vehicle direction.

5. The body according to claim 1 , wherein
the support element has a closed profile.

6. The body according to one of claim 1 , wherein
the support element has a profile which is open at precisely one side and thereby a hollow cross section which is open at the side and which is supplemented by the lateral sill or the A-pillar to form a closed hollow cross-section.

7. The body according to claim 1 , wherein
the support element is constructed in several pieces.

8. The body according to claim 7 , wherein
the support element is constructed in two pieces and has only two integrally constructed components which are constructed separately from each other and which are connected to each other.

9. The body according to claim 1 , wherein
the support element is a metal support element.

10. The body according to claim 9 , wherein
the support element is a steel support element.

11. A passenger motor vehicle comprising a body according to claim 1 .
