Programmable seat back damper assembly for seats

摘要

A programmable seat back damper assembly (10) for a motor vehicle includes a generally horizontal seat cushion portion (14) and a generally upright back portion (16) operatively connected to the seat cushion portion (14). The programmable seat back damper assembly (10) includes a recliner (26) for operative connection to the seat back portion (16) and the seat cushion portion (14). The programmable seat back damper assembly (10) also includes a damper (28,128) for operative connection to the seat back portion (16) and the seat cushion portion (14) and having a magneto-rheological (MR) fluid (48,148) therein. The programmable seat back damper assembly (10) further includes a controller (50) electrically connected to the damper (28,128) to control an apparent viscosity of the MR fluid (48,148) to increase and decrease damping of the damper (28,128) for adjusting an angle of the seat back portion (16) relative to the seat cushion portion (14).
