Patent number: 12011097Abstract: A seat assembly with an adjustable head restraint assembly capable of being adjusted based on an approximate stature or spatial location of an occupant in the seat assembly. A seat assembly may include a sensor in the seat to detect if an occupant is present. The sensor may include a plurality of bladders and pressure sensors, a radar system, or a neuro-monitoring sensor. The sensor may send a signal to a controller indicating the presence of an occupant. The controller may approximate the size and/or spatial location of the occupant and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to an in-use position. The controller may determine that an occupant is not present and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to a non-use position.Type: GrantFiled: September 29, 2020Date of Patent: June 18, 2024Assignee: LEAR CORPORATIONInventors: Arjun Yetukuri, Sajad Arabnejad, Bradley C.
