## Abstract

For the protection of the occupants of a vehicle in case of a lateral impact, restraints (3) are integrated in the side structure of the vehicle and are adapted to be automatically stretched to extend tautly on the inside across the window opening and are connected to an airbag unit (25) for protection in case of an impact, which unit is accommodated adjacent to the side structure of the vehicle.

## Claims

### Claim 1

An apparatus for proecting the occupants of a vehicle, in case of a lateral impact, comprising in combination restraining means, which are integrated in a side structure of the vehicle and which are adapted to be extended in case of a lateral impact by an automatically responding actuator, which causes traction means to stretch the restraining means to extend tautly on the inside across a window opening of the side structure, in combination with an airbag unit (25, 42) for protection in case of an impact, which unit is integrated in the side structure of the vehicle and the airbag (26) of which in its inflated state is disposed between the restraining means which extend tautly across the window opening (23, 40) and the occupant of the vehicle.

### Claim 2 (depends on 1)

A protecting apparatus according to claim 1, characterized in that the restraining means (3, 34) comprise a two-dimensional textile fabric, which is folded together and stowed away in a non-activated state.

### Claim 3 (depends on 2)

A protecting apparatus according to claim 2, characterized in that the restraining means (3, 34) comprise a woven or knitted or braided fabric or a net.

### Claim 4 (depends on 1)

A protecting apparatus according to claim 1, wherein the traction means (6, 7, 38) are guided and are adapted to be fixed when the restraining means (3, 34) have reached their activated state.

### Claim 5 (depends on 1)

A protecting apparatus according to claim 1, characterized in that the actuator (17, 37) consists of a pre-stressed spring element.

### Claim 6 (depends on 1)

A protecting apparatus according to claim 1, characterized in that the actuator (17, 37) comprises a fluid-operable piston-cylinder unit (15, 16).

### Claim 7 (depends on 1, 2, 3, 4, 5, 6)

A protecting apparatus according to one of the claims 1 to 6, characterized in that the airbag (26) of the unit (25, 42) for protection in case of an impact and the restraining means (3, 34) or the traction means (6, 7, 38) are firmly interconnected.

### Claim 8 (depends on 1)

A protecting apparatus according to claim 1, characterized in that the unit (25, 42) comprising an airbag and serving for protection in case of an impact is accommodated in the door.

### Claim 9 (depends on 1)

A protecting apparatus according to claim 1, characterized in that the unit (25, 42) serving for protection in case of an impact and comprising an airbag is accommodated adjacent to a floor side rail, a roof side rail, the door posts, intermediate post, a B post, or in that portion of the roof of the body of the vehicle which is adjacent to the roof side rail.
