Abstract
A securement arrangement for a seat belt closure of a three-point seat belt system in a vehicle comprises an anchor piece secured to the vehicle, a closure body, and a generally U-shaped closure body retaining assembly for mounting the closure body on the anchor piece. A spring disposed between a pair of U-forming legs of the closure body retaining assembly biases the closure body into its home position. A contact element emits a signal to be processed by an onboard signal processing unit when the closure body, due to the application thereto of a load imposed by the seat belt, is displaced so as to overcome the biasing force of the spring. The contact element correspondingly moves out of contact and emits a signal in response to its movement out of contact.
Claims21
A securement arrangement for a seat belt closure of a three-point seat belt system in a vehicle, comprising:
- an anchor piece secured to the vehicle;
- a closure body;
- a generally U-shaped closure body retaining assembly for mounting the closure body on the anchor piece, the closure body retaining assembly having a pair of U-forming legs;
- a biasing means for biasing the closure body into its home position, the biasing means being disposed between the pair of U-forming legs of the closure body retaining assembly;
- and
- a contact element for emitting a signal to be processed by an onboard signal processing unit, the closure body being displaceable relative to the closure body retaining assembly against the biasing force of the biasing means and the contact element being disposed such that, if the closure body, due to the application thereto of a load imposed by the seat belt, is displaced so as to overcome the biasing force of the biasing means, the contact element correspondingly moves out of contact and emits a signal in response to its movement out of contact.
