First Claim
1. A safety arrangement incorporating a seat-belt to protect an occupant of a vehicle seat, of the type wherein the seat-belt is part of a restraining system to restrain the occupant in a collision situation, the safety arrangement comprising a unit to create an output signal representative of the weight of the seat occupant, the unit producing the output signal in response to a first input signal (F) which is a function of a force applied to the seat-belt by the occupant in a collision, and a second input signal (ac) which is a function of the acceleration of the seat in the collision, the restraining system being controllable in response to the output signal to adjust the restraining force applied to the occupant.

Abstract
A safety arrangement incorporates a seat-belt (3) to protect an occupant (2) of a vehicle seat (1). A control unit (11) incorporates a calculator (18) to calculate the weight of the occupant (2) of the seat occupant, by comparing the force (6) applied to the seat-belt by the seat occupant with the acceleration (14) of the compartment. A controller (19) controls a restraining force applied to the seat occupant by the safety-belt and, possibly, additional force limiting or energy absorbing devices such as an air-bag (8).
