Abstract

An over slam bumper for a vehicle is provided and includes a buffer unit having one end protruding from an inner panel of the door toward a vehicle body and absorbing shock power between the vehicle body and the door. A mounting unit has one end fixed to another end of the buffer unit and another end thereof is inserted into a penetration aperture to fix the buffer unit to the inner panel. The mounting unit includes an insert flange inserted into the buffer unit and a support flange interconnected to the insert flange. An insert having one end integrally protrudes from a center of the support flange toward the penetration aperture and clips are integrally formed at the protruding end of the insert and are fixed while being locked to an inner circumferential surface of the penetration aperture when a predetermined portion thereof is inserted into the penetration aperture.

First claim

What is claimed is:

1. An over slam bumper for a vehicle, comprising:
a buffer unit having a first end that protrudes from an inner panel of a door toward a vehicle body and is configured to absorb shock power that occurs between the vehicle body and the door; and
a mounting unit having a first end fixedly mounted to a second end of the buffer unit and a second end inserted into a penetration aperture to fix the buffer unit to the inner panel,
wherein the mounting unit includes:
an insert flange inserted into the buffer unit;
a support flange interconnected to the insert flange at a position spaced apart from the insert flange at a predetermined interval to form a locking groove between the support flange and the insert flange and configured to support the second end of the buffer unit inserted into the locking groove;
an insert having a first end integrally protruding from a center of the support flange toward the penetration aperture; and
at least two clips integrally formed at the first end of the insert and fixed while being locked to an inner circumferential surface of the penetration aperture when a predetermined portion thereof is inserted into the penetration aperture,
wherein each clip is formed to be inclined in a cone shape in which a second end directed toward the support flange from a first end connected to the insert faces an outer side from a center of the insert, the second end of each clip is spaced apart and detached from the insert,
the clips are spaced apart from each other at a set angle along a circumference of the insert and are formed in at least a pair facing each other, in which an additional clip is disposed between the pair of clips, and
the additional clip has both the first end and the second end integrally and directly connected to the insert to prevent elastic deformation and includes a holder having a support groove.

2. The over slam bumper for a vehicle of claim 1 , wherein the buffer unit has an inside that includes an insertion groove enclosing an outer circumference of the insert flange and the second end of the buffer unit includes a mounting aperture connected to the insertion groove.

3. The over slam bumper for a vehicle of claim 1 , wherein the second end of the buffer unit is integrally provided with protruding ends that contact the inner panel while the protruding ends integrally protrude toward the inner panel along a circumference of an outer circumferential surface.

4. The over slam bumper for a vehicle of claim 3 , wherein the support flange has an outer circumferential end partially inserted into the protruding end and includes support protrusion that protrudes from an inside of the protruding end toward the inner panel.

5. The over slam bumper for a vehicle of claim 4 , wherein the support protrusions are each formed at a position spaced apart from each other at a set angle along a circumference of the support flange based on a center of the insert.

6. The over slam buffer for a vehicle of claim 1 , wherein the second end of each clip includes a support groove that supports the inner panel when the clip is locked by being inserted into an inner circumferential surface of the penetration aperture.

7. The over slam buffer for a vehicle of claim 1 , wherein the support flange has a cross shape.

8. The over slam buffer for a vehicle of claim 1 , wherein the buffer unit and the mounting unit are made of different materials.

9. The over slam buffer for a vehicle of claim 1 , wherein the buffer unit is made of a thermo plastic elastomer (TPE) material.

10. The over slam buffer for a vehicle of claim 1 , wherein the mounting unit is made of a poly oxy methylene (POM) material and is molded by injection molding.

11. The over slam buffer for a vehicle of claim 6 , wherein each support groove bears a predetermined amount of load transferred from the inner panel to transfer the load to the buffer unit in an alleviated state.
