Abstract

A front section for a motor vehicle includes a bumper cladding and a bumper stiffening which extends in the vehicle longitudinal direction between the bumper cladding and a supporting body part. A connecting unit including a blind nut and a threaded fastener is inserted from below into an opening of the body part to fix a rear edge region of the bumper stiffening on an underside of the body part. The blind nut has flexible legs which are reversibly splayed apart above the opening.

First claim

1 - 15 . (canceled)

16 . A front section for a motor vehicle comprising:
a bumper stiffener configured to extend in the vehicle longitudinal direction between a bumper cladding and a body part; and a connecting unit configured to fix a rear edge region of the bumper stiffener to an underside of the body part, the connecting unit having a threaded fastener and blind nut for inserting into an opening of the body part and receiving the threaded fastener, wherein a flexible leg formed on the blind nut is reversibly splayed apart when the threaded fastener is received in blind nut.

17 . The front section according to claim 16 , wherein the blind nut includes the flexible leg which are splayed apart by screwing the threaded fastener into a thread of the blind nut.

18 . The front section according to claim 17 , wherein the blind nut comprises a base plate having the thread formed therein, wherein the flexible leg extends from an edge of the base plate.

19 . The front section according to claim 18 , wherein the flexible leg comprises a plurality of legs, each leg comprising a distal section and a proximal section connecting the distal section to the base plate, wherein at least two proximal sections diverge from the base plate.

20 . The front section according to claim 16 , wherein the bumper stiffener comprises sliding surfaces to provides the body part when the bumper stiffener is moved rearward relative to the body part.

21 . The front section according to claim 20 wherein the sliding surface is inclined towards the vehicle interior.

22 . The front section according to claim 20 , wherein the bumper stiffener comprises a base plate and a stiffening rib projecting upwards from the base plate, wherein the sliding surface is formed by an edge of the rib.

23 . The front section according to claim 16 , wherein the bumper stiffener comprises a projection in a flank opposite a front side of the body part and a recess formed underneath the projection, wherein the projection is configured to contact the front side at least when the bumper stiffener is moved rearward relative to the body part.

24 . The front section according to claim 23 , wherein the bumper stiffener comprises a base plate and a stiffening rib projecting upwards from the base plate, wherein the flank is formed by a rear end of the ribs.

25 . The front section according to claim 22 , wherein the rib is stiffened by a wing projecting in the vehicle transverse direction.

26 . The front section according to claim 25 , wherein the wing is connected in one piece to the base plate at a front edge.

27 . The front section according to claim 25 , wherein the wing extends to a rear end of the rib.

28 . The front section according to claim 25 , wherein the wing is tapered towards a rear edge thereof.

29 . The front section according to claim 16 , wherein the bumper stiffener is curved in longitudinal section with an upwardly facing concavity.

30 . The front section according to claim 16 , wherein the bumper stiffener includes a front portion configured to cross under at least a front part of an engine compartment.

31 . The front section according to claim 30 , wherein the front portion is configured to cover a radiator.
