Abstract

An impulse detector includes a piezoelectric component and a resilient component. The resilient component has a predetermined resistance to deformation during an impact. The piezoelectric component is associated with the resilient component so that an impulse of a predetermined magnitude causes deformation of the piezoelectric component thereby generating a resulting electrical signal. An impulse responsive vehicle seat assembly incorporates the impulse detector to detect vehicle collisions.

Description

technical field [0001] The present invention relates to a piezoelectric impulse detector effective for sensor vehicle impacts. More particularly, the present invention relates to a piezoelectric shock detector incorporated into a shock responsive vehicle seat assembly. Background technique [0002] Modern vehicle designs need to comply with many government regulations. In particular, the regulations on vehicle safety requirements are complete. Regulations on a vehicle's response to a crash have been particularly successful in reducing harmful effects on vehicle occupants. The trend is for newer vehicles to meet stricter safety requirements. [0003] Recently, the regulation FMVSS 202A was adopted for the design of head restraints. The FMVSS 202A is tuned to minimize whiplash injury during low speed (10-15 km / h) rear end collisions. In such a collision, the occupant's head moves backwards and then forwards, thereby injuring the tissues within the neck. Front seats must ...
