Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 233 words
A vehicle comprising: a chassis having a passenger compartment with a floor and a door which can be moved between an open position and a closed position; a seat assembly located near said door in said passenger compartment; a sliding mechanism mounted on said floor of said vehicle and supporting said seat assembly for permitting sliding movement of said seat assembly in a fore-and-aft direction relative to said floor; and a rigid member secured to said seat assembly to move therewith, said rigid member extending toward the door in said closed position, said rigid member having a leading end portion with a flat section which is substantially parallel with a portion of a surface of said closed door and which is positioned adjacent to said portion and spaced from said portion by a predetermined distance such that upon movement of said door inward of said passenger compartment beyond said closed position, said door contacts said flat section, said rigid member being attached between said seat assembly and said sliding mechanism for mounting said seat assembly on said sliding mechanism, whereby during a collision, when said door is pushed into said passenger compartment by an external force applied thereto, said door is brought into engagement with said flat section of said rigid member thereby either preventing further inward motion of said door or moving said seat assembly in response to movement of said door.
