HEAD RESTRAINT WITH A MULTI-CELL BLADDER ASSEMBLY

摘要

A vehicle seating assembly includes a pump and a headrest. The headrest has a support base, a flexible foam layer coupled with the support base, a flexible substrate overlying the foam layer and defining an outer surface, and an inflatable bladder assembly positioned between the base and the foam layer. The bladder assembly has a plurality of cells corresponding to respective regions of the outer surface that are independently operable between inflated and deflated conditions by the pump. The seating assembly further includes a control operably coupled to the pump.

1. A vehicle seating assembly, comprising:
a pump; a headrest, including:
a support base including first and second support arms, the second support arm having a channel therethrough;a flexible foam layer coupled with the support base;a flexible substrate overlying the foam layer and defining an outer surface;a fluid manifold between the base and the foam layer, the fluid manifold being coupled with the pump by an air supply line extending through the channel and including a plurality of valves;an inflatable bladder assembly positioned between one of the base and the foam layer or the foam layer and the substrate and having a plurality of cells corresponding to respective regions of the outer surface and coupled with the pump through the fluid manifold with the plurality of cells respectively associated with the plurality of valves to be independently operable between inflated and deflated conditions by the pump; and a control operably coupled to the pump and the fluid manifold.
