Integrated lumbar and active headrest system

摘要

An integrated active headrest/lumbar seating system (22) includes an active headrest system (10) supported within a seat frame (12) of a vehicle. The active headrest system (10) includes an energy transfer mechanism (14) that connects the headrest (16) to the lumbar support (18). The lumbar support (18) is operated by an actuator (20). The energy transfer mechanism (14) includes a pair of linkages (26), a pair of side bars (30) and a crossbar (34). The linkages (25) connect to the headrest (16) and the pair of side bars (30) extend from the pair of linkages (26) along the side rails (32) of the seat frame (12) to the crossbar (34). The crossbar (34) connects the pair of side bars (30) and is situated at the middle section (40) of the lumbar support (18). The lumbar support (18) can fit between the side bars (30).
