Abstract

A front module for a motor vehicle includes two longitudinal members arranged one on either side, a bumper sitting in front of the two longitudinal members and connected to front ends of the longitudinal members with the interconnection of a respective deformation element, and a radiator frame arranged between the longitudinal members and supporting the cooling assembly. In a collision, the bumper, after the deformation of the deformation element, comes to bear against the radiator frame, wherein the radiator frame can then be displaced for a limited distance to the rear in the direction of the passenger compartment. After displacement or deformation of the radiator frame, the bumper (1) comes to bear against at least one point of the cooling assembly (5) in order to displace the latter to the rear in the direction of the passenger compartment.

Claims

1. A front module for a motor vehicle with two longitudinal members (3) arranged one on either side, a bumper support (1) which sits in front of the two longitudinal members (3) and is connected to the front ends of the longitudinal members (3) with the interconnection of a respective deformation element (2), and a radiator frame (4) which is arranged between the longitudinal members (3) and between the deformation members (2) and supports the cooling assembly (5),

wherein,

in the event of a collision, the bumper support (1) first of all, in a first deformation stage after the deformation of the deformation element (2) or of the deformation elements, comes to bear against the radiator frame (4), wherein the radiator frame (4) can then be displaced for a limited distance to the rear in the direction of the passenger compartment, and wherein, after displacement or deformation of the radiator frame (4) in a second stage, the bumper support (1) comes to bear against at least one point of the cooling assembly (5) in order to displace the latter to the rear in the direction of the passenger compartment.

2. The front module as claimed in claim 1, wherein, for the first deformation stage, the displacement distance of the radiator frame (4) is limited by the latter striking against the lower frame part (8).

3. The front module as claimed in claim 1, wherein the radiator frame (4) can be deformed per se.

4. The front module as claimed in claim 1, wherein the bumper support (1), upon movement thereof to the rear at the beginning of the second deformation stage, comes to bear against the distributor box (6) of the cooling assembly (5).

5. The front module as claimed in claim 4, wherein, on both sides of the cooling assembly (5), a respective contact block (7) is arranged on the distributor box (6) level with the bumper support (1), against which contact block the bumper support (1) comes to bear at the beginning of the second deformation stage upon displacement of said bumper support to the rear.

6. The front module as claimed in claim 5, wherein the contact block (7) is composed of elastic material.

7. The front module as claimed in claim 1, wherein the radiator frame is designed so as to arch convexly toward the front side of the vehicle.

8. The front module as claimed in claim 2, wherein the radiator frame (4) can be deformed per se.

9. The front module as claimed in one of claim 2, wherein the bumper support (1), upon movement thereof to the rear at the beginning of the second deformation stage, comes to bear against the distributor box (6) of the cooling assembly (5).

10. The front module as claimed in one of claim 3, wherein the bumper support (1), upon movement thereof to the rear at the beginning of the second deformation stage, comes to bear against the distributor box (6) of the cooling assembly (5).

11. The front module as claimed in claim 2, wherein the radiator frame is designed so as to arch convexly toward the front side of the vehicle.

12. The front module as claimed in claim 3, wherein the radiator frame is designed so as to arch convexly toward the front side of the vehicle.

13. The front module as claimed in claim 4, wherein the radiator frame is designed so as to arch convexly toward the front side of the vehicle.

14. The front module as claimed in claim 5, wherein the radiator frame is designed so as to arch convexly toward the front side of the vehicle.

15. The front module as claimed in claim 6, wherein the radiator frame is designed so as to arch convexly toward the front side of the vehicle.
