Problems solved by technology

For example, some parts need to be considered as discrete components according to traditional design methods, but when the design process is considered differently, some discrete components can actually be replaced by other devices that can perform the same function, thereby Make traditional discrete components redundant

Embodiment Construction

[0022] Referring to the drawings, wherein like numerals refer to like elements, the various embodiments described below with reference to corresponding figures are for an active head restraint system 10 suitable for installation in a seat frame 12 of any vehicle. In FIGS. 1 and 2 , the active head restraint system 10 is shown including an energy transfer mechanism 14 connecting a head restraint 16 to a lumbar support device 18 . The lumbar support 18 is operated by an actuator 20 . In general, the active head restraint system 10 incorporating the seat frame 12 and the actuator 20 is an integrated active head restraint / lumbar support seating system 22 .

[0023] At the upper end 24 of the seat frame 12 , a pair of linkages 26 connect the energy transfer mechanism 14 to the headrest 16 , which is supported at the upper end 24 by a top beam 28 . A pair of side bars 30 extend from the corresponding pair of links 26 along a side beam 32 of the seat frame 12 to a cross bar 34 . Th...

Abstract

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 cross bar (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).

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 60 / 567,238, filed April 30, 2004, which is hereby incorporated by reference. [0003] Statement Regarding Federally Funded Research and Development Programs [0004] Not applicable [0005] appendix [0006] Not applicable technical field [0007] The present invention relates generally to active (seat) head restraint systems, and more particularly to active head restraint systems with lumbar support. Background technique [0008] Active head restraint systems (AHRS) with energy transfer mechanisms are generally known and improved in seat support systems for increasing the safety of vehicle occupants in the event of a collision In order to reduce the injury to the passenger's neck. In the event of a rear impact, the seat occupant in the vehicle is forcibly pressed against the seat. Generally speaking, initially the passenger's pelvis and lumbar...
