Device for passenger protection in a vehicle
First Claim
1. A device for protection of passengers in vehicles with at least one seat arranged in connection to the rear part of the vehicle, which seat is arranged so that said passenger, when travelling in the seat, faces said rear part, comprising at least one inflatable element, a sensor for detecting a predetermined collision-like state of the vehicle and means for inflating the element in case of said state, wherein said element in an inactive, non-inflated state is arranged in connection to the two upper and rear corners of the body structure of the vehicle, where in the element in an active, inflated state is arranged so as to expand away from said corners in a direction towards the vertical line of symmetry of the vehicle, thereby assuming a position between said passenger and said rear part.

Abstract
The invention relates to a device for protecting passengers (5) in vehicles (1) with at least one seat (4) arranged in connection to the rear part of the vehicle (1), which seat is arranged so that said passenger (5) when travelling in the seat (4) faces said rear part, comprising at least one inflatable element (6; 6'"'"'), a sensor for detecting a predetermined collision-like state of the vehicle (1), and means (8) for inflating the element (6; 6'"'"') in case of said state. The invention is characterized in that said element (6; 6'"'"') in an inactive, non-inflated state is arranged in connection to said rear part and, in an active, inflated state is arranged to assume an extension between said passenger and said rear part. By means of the invention, an improved airbag device for protecting passengers in a rearwards facing extra seat in a vehicle is provided.

- 1. A device for protection of passengers in vehicles with at least one seat arranged in connection to the rear part of the vehicle, which seat is arranged so that said passenger, when travelling in the seat, faces said rear part, comprising at least one inflatable element, a sensor for detecting a predetermined collision-like state of the vehicle and means for inflating the element in case of said state, wherein said element in an inactive, non-inflated state is arranged in connection to the two upper and rear corners of the body structure of the vehicle, where in the element in an active, inflated state is arranged so as to expand away from said corners in a direction towards the vertical line of symmetry of the vehicle, thereby assuming a position between said passenger and said rear part.
- 5. A device for protection of passengers in vehicles with at least one seat arranged in connection to the rear part of the vehicle, which seat is arranged so that said passenger, when travelling in the seat, faces said rear part, comprising at least one inflatable element, a sensor for detecting a predetermined collision-like state of the vehicle and means for inflating the element in case of said state, wherein said element in an inactive non-inflated state is arranged in connection to said rear part, and in an active inflated state is arranged to assume an extension between said passenger and said rear part.

9. A device for protecting passengers in a vehicle of the station wagon kind which comprises a seat arranged in the luggage compartment of the vehicle, which seat faces rearwards, with said passengers, when travelling in the seat, thus facing the rear end part of the vehicle, comprising at least one inflatable element, a sensor for detecting a predetermined collision-like state of the vehicle, and means for inflating said element in case of said state, wherein said element in an inactive, non-inflated state, is arranged in connection to said rear end part, and in an active inflated state is arranged to assume an position between said passenger and said rear end part, thereby forming a curtain having a thickness which is considerably smaller than its width and length.
-
10. A method for protecting passengers in vehicles with at least one seat arranged in connection to the rear part of the vehicle, said seat being arranged so that said passenger when travelling in the seat faces said rear part, and at least one inflatable element, comprising
detecting a predetermined collision-like state of the vehicle and inflating the element in case of said state, wherein said inflation of the element is controlled so that the element expands away from the two upper and rear corners of the body structure of the vehicle and in a direction towards the vertical line of symmetry of the vehicle, the element thereby assuming a position between said passenger and said rear part.
