Abstract

A device is proposed for transmitting data or energy to a system of restraint in a vehicle, which is used for connecting movable vehicle parts by a transformer. According to the present invention, a reed contact is provided on the secondary side of the transformer which short-circuits the winding or the coil when the movable part is removed. This prevents an induction voltage from leading to an undesired triggering of the means of restraint.

Claims

1. A device for data and/or energy transmission to means of restraint in a vehicle, the device having a transformer (2) which has its primary side (3) in a first vehicle part and its secondary side (4) in a second vehicle part;

the first and/or secondary vehicle part being removable,

wherein the secondary side (4) has a reed contact (5) and the primary side has a magnet (6), the reed contact closing so as to short-circuit the winding of the secondary side (4) when the first vehicle part is removed.

2. The device as recited in claim 1,

wherein the first vehicle part is designed as the chassis and the second vehicle part is designed as a seat.

3. The device as recited in claim 1 or 2,

wherein the means of restraint (15), means (13, 12) for diagnosis and for controlling the means of restraint (15), are situated on the secondary side.
