Abstract
Abstract A vehicle door whose inside is deformable under energy dissipation. The inside is thereby subdivided into different sections matched in its rigidity to the individual body regions of the passenger. Furthermore, the rigidity can increase toward the rear door frame so that taller vehicle passengers find altogether a more rigid door inside when the seat is displaced toward the rear. The vehicle door is to reduce the injury risks in case of a lateral impact.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
120 words
A vehicle side door having inside energy dissipating section means facing a vehicle seat and constructed to be variably deformable along its height under energy dissipation in case of an impact of a body of a passenger seated on the vehicle seat, wherein the the energy dissipation sections means has portions with varying rigidity and wherein the rigidity of these portions is matched to differing resistance capabilities of individual adjacent body regions of a vehicle passenger to safely accept an impact and has smaller rigidity values in the area located adjacent where an abdominal area of a vehicle passenger sitting on the seat would be located than in the area adjacent where the pelvis and chest area would be located.
Claim 2
Dependent Claim
120 words
A vehicle side door having inside energy dissipating section means facing a vehicle seat and constructed to be variably deformable along its height under energy dissipation in case of an impact of a body of a passenger seated on the vehicle seat, wherein the the energy dissipation sections means has portions with varying rigidity and wherein the rigidity of these portions is matched to differing resistance capabilities of individual adjacent body regions of a vehicle passenger to safely accept an impact and has smaller rigidity values in the area located adjacent where an abdominal area of a vehicle passenger sitting on the seat would be located than in the area adjacent where the pelvis and chest area would be located.
Claim 3
Dependent Claim
48 words
A vehicle door according to claim 1, wherein said vehicle seat is adjustable in the vehicle longitudinal direction and wherein there are differing rigidity values of the energy dissipating means inside of the door, which increase in value in the direction toward the rear edge of the door.
