Energy redn. system for use with vehicle seat arrangement - involves framework fitted to vehicle frame and supporting slidable seat base, system supporting seat base in predetermined position relatively to framework

摘要

The arrangement permits a lift of the seat base (18) relatively to the framework (20) in a predetermined direction dependent upon a force component which is parallel to the predetermined direction and has a specific dim. A force transmitted to a person sitting on the seat base is reduced to an acceptable level. An energy redn. system (34) responding to an exerted load adjusts the amt. of the force redn. provided dependent upon the wt. of the person sitting on the seat base (18). A further arrangement prevents the lifting of the seat base when no force component is present, whereby the seat base (18) is retained in a fixed position in relation to the framework. USE/ADVANTAGE - To enhance the safety of passengers in motor vehicles in the event of a crash.
