Abstract
A lateral impact protective device for a front and a rear vehicle occupant comprises an elongated head gas bag which is convertable from a folded state to an inflated state. The gas bag has two opposite lateral ends and is adapted to extend, in the inflated state, from sidewards of said front vehicle occupant as far as sidewards of said rear vehicle occupant. The lateral protective device provides a common and, therefore, low-price protection for the front and the rear vehicle occupant.

A lateral impact protective device for a front vehicle occupant and a rear vehicle occupant of a vehicle, the vehicle including an A-pillar, a roof frame, and a C-pillar, said lateral impact protective device comprising:
- an elongated head gas bag which is convertible from a folded state to an inflated state, said gas bag having two opposite lateral ends and being adapted to extend, in the inflated state, from sidewards of the front vehicle occupant as far as sidewards of the rear vehicle occupant, said gas bag having gas inlet openings at least at one of said lateral ends;
- and
- at least one gas generator, said gas generator being attached to at least one of the A-pillar and the C-pillar of the vehicle and being connected via said gas inlet openings with the interior of said gas bag.
A lateral impact protective device for a front vehicle occupant and a rear vehicle occupant of a vehicle, said lateral impact protection device comprising:
- an elongated head gas bag which is convertible from a folded state to an inflated state, said gas bag having two opposite lateral ends and being adapted to extend, in the inflated state, from sidewards of the front vehicle occupant as far as sidewards of the rear vehicle occupant;
- and
- a hose-like fitting sheath in which said head gas bag is arranged in the folded state thereof.
A lateral impact protective device for a front vehicle occupant and a rear vehicle occupant of a vehicle, said lateral impact protection device comprising:
- an elongated head gas bag which is convertible from a folded state to an inflated state, said head gas bag having two opposite lateral ends and being adapted to extend in a longitudinal direction, in the inflated state, from a sidewards of the front vehicle occupant as far as sidewards of the rear vehicle occupant;
- said head gas bag having at least one element adapted to partially constrict said head gas bag in said inflated state thereof, said element extending transverse to said longitudinal direction and shortening said head gas bag in said longitudinal direction during inflation.
