Abstract
A vehicle door includes an inner panel, an outer panel joined to the inner panel and a door trim panel mounted on the inner panel to form a space therebetween. The vehicle door also includes a honeycomb shaped energy absorbing structure disposed in the space between the door trim panel and the inner panel for absorbing energy from a side collision type impact of the vehicle door.
Claims20
A vehicle door comprising:
- an inner panel;
- an outer panel joined to said inner panel;
- a door trim panel mounted on said inner panel to form a space therebetween;
- and
- a pre-crushed honeycomb shaped energy absorbing structure disposed in the space between said door trim panel and said inner panel for absorbing energy from a side collision type impact of said vehicle door.

A vehicle door comprising:
- an inner panel;
- an outer panel joined to said inner panel;
- a door trim panel mounted on said inner panel to form a space therebetween;
- a honeycomb shaped energy absorbing structure disposed in the space between said door trim panel and said inner panel for absorbing energy from a side collision type impact of said vehicle door;
