Safety device for a vehicle with a removable seat, especially a passenger seat
First Claim
1. Safety device for a vehicle with a removable seat, comprising:
- an occupant restraint device associated with said seat, said occupant restraint device comprising at least one airbag and being triggerable in the event of a serious accident by a triggerable signal from a triggering control device so that the restraint device assumes a restraint position that protects the occupant;
a seat occupation device located in the seat that detects a variable seat occupation status and delivers a corresponding seat occupation status signal through a signal interface to the triggering control device located in the vehicle, which takes the seat occupation status into account in issuing the triggering signal;
a seat installation detection device that detects proper installation of the seat and delivers a corresponding seat installation status signal;
an interface interrogation unit that checks the transmission capability of at least a signal interface and delivers a corresponding interface status signal;
wherein the triggering control device is configured to take into account the status signals for seat occupation, interface, and seat installation in such fashion that the scope of the triggering of the restraint device is adapted to the conditions characterized by the status signals.

Abstract
A safety device is provided for a vehicle with a removable seat, especially a passenger seat, with an occupant restraint device associated with the seat. In addition, a seat occupation detection device located in the seat is provided that detects various states of seat occupation, especially by a person or by a child seat, and delivers a corresponding seat occupation status signal through a signal interface to a triggering control device located in the vehicle. The triggering control device takes the seat occupation status into account in delivering the triggering signal, especially to determine the scope of triggering of the restraint device. A seat installation detection device is provided that detects the proper installation of the seat and delivers a corresponding seat installation status signal to the triggering control device. The status signal permits the triggering control device, through a logical link with another status signal that indicates the correct signal transmission at the signal interface, to detect the actual presence or absence of the seat as well as a variety of defective states and to adjust accordingly the delivery of the triggering signal emitted in the case of a serious accident.
