Abstract
Abstract A door inner panel and a door outer panel attached together in spaced apart relation defining a cavity. The door inner panel has an opening therein and the door components such as the window regulator and door handles are mounted on the module panel. A plurality of energy absorbing devices extended between the module panel and the door inner panel to effectively mount the module panel within the opening of the door inner panel. The energy absorbing devices yield upon the imposition of an occupant thereagainst to enable energy absorbing movement of the module panel and the door components into the cavity space between the inner and outer panels. The energy absorbing devices are preferably comprised of stamped steel straps having convolutions therein with one end of the strap welded to the module panel and the other end bolted to the door inner panel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A vehicle door comprising: a door inner panel and door outer panel attached together to form a door hingedly mounted on the vehicle body, said inner panel having an opening therein, a module panel having door components mounted thereon and adapted for mounting in the inner panel within the opening of the inner panel, and a plurality of energy absorbing means extending between the module panel and the door inner panel to effectively mount the module panel on the door and enable energy absorbing movement of the module panel relative to the door upon impact of the occupant against the door.
Claim 2
Dependent Claim
101 words
A vehicle door comprising: a door inner panel and door outer panel attached together to form a door hingedly mounted on the vehicle body, said inner panel having an opening therein, a module panel having door components mounted thereon and adapted for mounting in the inner panel within the opening of the inner panel, and a plurality of energy absorbing means extending between the module panel and the door inner panel to effectively mount the module panel on the door and enable energy absorbing movement of the module panel relative to the door upon impact of the occupant against the door.
Claim 3
Dependent Claim
124 words
A vehicle door comprising: a door inner panel and door outer panel attached together in spaced apart relation to form a cavity within the door, said inner panel having an opening therein, a module panel having door components mounted thereon and adapted for mounting within the opening in the inner panel to thereby mount the door components on the door, and a plurality of energy absorbing means extending between the module panel and the door inner panel to effectively mount the module panel on the door, said energy absorbing means being operable upon the imposition of an occupant thereagainst to enable energy absorbing movement of the module panel and the door components into the cavity space between the inner panel and the outer panel.
Claim 4
Dependent Claim
124 words
A vehicle door comprising: a door inner panel and door outer panel attached together in spaced apart relation to form a cavity within the door, said inner panel having an opening therein, a module panel having door components mounted thereon and adapted for mounting within the opening in the inner panel to thereby mount the door components on the door, and a plurality of energy absorbing means extending between the module panel and the door inner panel to effectively mount the module panel on the door, said energy absorbing means being operable upon the imposition of an occupant thereagainst to enable energy absorbing movement of the module panel and the door components into the cavity space between the inner panel and the outer panel.
Claim 5
Dependent Claim
123 words
A vehicle door comprising: a door inner panel and door outer panel attached together in spaced apart relation to form a door hingedly mounted on the vehicle body, said inner panel having an opening therein, a module panel having door components mounted thereon and adapted for mounting within the opening in the inner panel to thereby mount the door components on the door, and a plurality of yieldable straps extending between the module panel and the door inner panel to effectively mount the module panel on the door, said yieldable straps yielding upon the imposition of an occupant thereagainst to enable energy absorbing movement of the module panel and the door components into the space between the inner panel and the outer panel.
Claim 6
Dependent Claim
123 words
A vehicle door comprising: a door inner panel and door outer panel attached together in spaced apart relation to form a door hingedly mounted on the vehicle body, said inner panel having an opening therein, a module panel having door components mounted thereon and adapted for mounting within the opening in the inner panel to thereby mount the door components on the door, and a plurality of yieldable straps extending between the module panel and the door inner panel to effectively mount the module panel on the door, said yieldable straps yielding upon the imposition of an occupant thereagainst to enable energy absorbing movement of the module panel and the door components into the space between the inner panel and the outer panel.
Claim 7
Dependent Claim
29 words
The combination of claim 3 in which said yieldable straps have convolutions formed therein by which the yieldable straps are extended in length by plastic deformation of said convolutions.
