Vehicle occupant restraint apparatus
First Claim
1. Apparatus comprising:
- a vehicle seat having a cover extendible from an initial condition to an extended condition;
said seat having a first volume enclosed by said cover when said cover is in said initial condition and having a second, greater volume enclosed by said cover when said cover is in said extended condition, said second enclosed volume being greater than said first enclosed volume sufficiently for enlargement of said seat from said first enclosed volume to said second enclosed volume to enhance the degree to which said seat can restrain movement of a seated vehicle occupant under the influence of vehicle crash forces; and
an inflatable vehicle occupant protection device supported on said seat for movement against said cover so as to extend said cover from said initial condition to said extended condition upon inflation of said protection device from a stored condition to a fully deployed condition.

Abstract
An apparatus (10) includes a vehicle seat (12) having a cover (32) which is extendible from an initial condition to an extended condition for restraining an occupant of the seat (12). The seat (12) has a first volume enclosed by the cover (32) when the cover (32) is in the initial condition. The seat (12) has a second, greater volume enclosed by the cover (32) when the cover (32) is in the extended condition. The second enclosed volume of the seat (12) is greater than the first enclosed volume sufficient for enlargement of the seat (12) from the first enclosed volume to the second enclosed volume to enhance the degree to which the seat (12) can restrain movement of a seated vehicle occupant under the influence of vehicle crash forces. An inflatable vehicle occupant protection device (18) is supported on the seat (12). The protection device (18) is movable against the cover (32) so as to extend the cover (32) from the initial condition to the extended condition upon inflation of the protection device (18) from a stored condition to a fully deployed condition.
