Abstract

Claims (20)

1. A method of assembling a modular bumper shell comprising:

providing an attachment member adapted for attachment to an energy-absorbing vehicle bumper substructure;

providing at least two outer members, at least one of said outer members being selectively detachable from said attachment member without detaching said attachment member from said energy-absorbing vehicle bumper substructure or detaching the other of said outer members from said attachment member;

attaching said at least two outer members directly to said attachment member such that said at least two outer members are at least partially visible from a vehicle exterior following vehicle assembly; and

attaching a step pad member to said attachment member, whereby said attachment member is rendered nonvisible from the vehicle exterior following vehicle assembly.

2. The method of claim 1 , wherein at least one of said at least two outer members is replaceable by a modified outer member, thereby changing the appearance of said modular bumper shell without replacing said attachment member.

3. The method of claim 1 , wherein said attachment member may be used with a plurality of different outer members.

4. The method of claim 1 , further comprising:

removing at least one of said outer members; and

attaching a modified outer member, thereby changing the appearance of said modular bumper shell.

5. A modular bumper shell comprising:

an attachment member adapted for attachment to an energy-absorbing vehicle bumper substructure;

at least two outer members affixed directly to and at least partially covering said attachment member, at least one of said outer members being detachable from said attachment member without detaching said attachment member from said energy absorbing vehicle bumper substructure or detaching the other of said at least two outer members from said attachment member; and

a step pad member affixed to and at least partially covering said attachment member, wherein said attachment member is thereby rendered nonvisible from the vehicle exterior following vehicle assembly.

6. The modular bumper shell of claim 5 , wherein said attachment member is formed from a material sufficient to provide structural support to said modular bumper shell.

7. The modular bumper shell of claim 5 , wherein said at least two outer members are formed from one of cold-rolled steel, hot-formed steel, extruded steel, extruded aluminum, and high-strength plastic.

8. The modular bumper shell of claim 5 , wherein said step pad member has an outer surface with an appearance finish that is visible from the vehicle exterior.

9. The modular bumper shell of claim 5 , wherein said at least two outer members each have a respective outer surface with an appearance finish, and wherein said attachment member is characterized by the absence of an outer surface with an appearance finish.

10. The modular bumper shell of claim 5 , wherein at least one outer member is replaceable by a modified outer member, thereby changing the appearance of said modular bumper shell without replacing said attachment member.

11. The modular bumper shell of claim 5 , wherein said attachment member may be used with a plurality of different outer members.
