## Abstract

A vehicle is provided including a bumper attachment member, a radiator support beam, and a bumper support assembly coupled to the bumper attachment member and the radiator support beam. The bumper support assembly includes a center stay fixed to the radiator support beam and a center stay support having a receiver, an arm, and an anti-rotation pin. The arm extends in a vehicle-longitudinal direction from the receiver. The receiver is configured to receive and engage the bumper attachment member. The anti-rotation pin extends in the vehicle-lateral direction proximate an end of the arm opposite the receiver and engages the center stay to inhibit movement of the bumper attachment member with respect to the radiator support beam.

## Claims

### Claim 1

A vehicle comprising:
a bumper attachment member;
a radiator support beam; and
a bumper support assembly coupled to the bumper attachment member and the radiator support beam, the bumper support assembly comprising:
a center stay fixed to the radiator support beam; and
a center stay support having a receiver, an arm, and an anti-rotation pin, the arm extends in a vehicle-longitudinal direction from the receiver, the receiver configured to receive and engage the bumper attachment member, the anti-rotation pin extends in a vehicle-lateral direction proximate an end of the arm opposite the receiver and engages the center stay to inhibit movement of the bumper attachment member with respect to the radiator support beam.

### Claim 2 (depends on 1)

The vehicle of claim 1, wherein the receiver defines a channel for receiving an end of the bumper attachment member, an opposite end of the bumper attachment member being fixed to a bumper.

### Claim 3 (depends on 1)

The vehicle of claim 1, wherein the center stay includes a ledge and the receiver of the center stay support has a seat, the seat abutting against the ledge to inhibit movement of the bumper attachment member in the vehicle-vertical direction with respect to the radiator support beam.

### Claim 4 (depends on 3)

The vehicle of claim 3, wherein the anti-rotation pin extends through an anti-rotation aperture formed in the center stay.

### Claim 5 (depends on 4)

The vehicle of claim 4, wherein the center stay support includes a locking pin extending from the seat and extending through a locking aperture formed in the ledge of the center stay.

### Claim 6 (depends on 5)

The vehicle of claim 5, wherein the anti-rotation pin includes a plus-shaped cross-section.

### Claim 7 (depends on 5)

The vehicle of claim 5, wherein the center stay has a rear end coupled to the radiator support beam and a forward end opposite the radiator support beam, the anti-rotation aperture formed proximate the rear end of the center stay and the locking aperture formed proximate the forward end of the center stay.

### Claim 8 (depends on 6)

The vehicle of claim 6, wherein the anti-rotation aperture and the locking aperture have a cross-section corresponding to the anti-rotation pin and the locking pin, respectively.

### Claim 9 (depends on 1)

The vehicle of claim 1, wherein the receiver, the arm, and the anti-rotation pin are formed as a one-piece, monolithic structure.

### Claim 10 (depends on 5)

The vehicle of claim 5, wherein the locking pin extends in a vehicle-vertical direction.

### Claim 11 (depends on 10)

The vehicle of claim 10, wherein the anti-rotation pin extends in a direction perpendicular to a direction in which the locking pin extends.
