Embodiment Construction

[0036] Before any embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in application to the details of construction and arrangement of parts set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways.

[0037] refer to figure 1 and 2 , the seat 10 generally includes a seat bottom 14 and a seat back 18 to support a seat occupant horizontally and vertically, respectively. The frame 22 covered by the covered pad 26 provides structural integrity to the seat 10 and includes a seat back frame portion 30 and a seat bottom frame portion 34 . Herein, seat 10 will be described as a vehicle seat in a passenger compartment of a vehicle, but is not limited to vehicle applications.

[0038] Seat 10 includes a plurality of support members that are adjustable by the user for added comfort and support. also refer to imag...

Abstract

A pneumatically adjustable seat includes: a seat frame having a seat back frame portion; and a headrest coupled to the seat back frame portion. The headrest includes a resilient pad. The driver assembly includes a contact member operatively connected to the resilient pad. A first bladder is operably coupled to the contact member and is in fluid communication with a source of pressurized fluid. Inflating the first bladder by the source of pressurized fluid causes the contact member to extend from a first position closer to the seat back frame to a second position further from the seat back frame. A second bladder is operatively coupled to the contact member and in fluid communication with the source of pressurized fluid. Inflating the second air bag by the source of pressurized fluid pivots the contact member away from the seat occupant.

Description

technical field [0001] The present invention relates to a seat having an adjustable cushion that supports the head and thighs of a passenger. Background technique [0002] Seat adjustability is a desirable feature in vehicles in order to adequately accommodate a wide range of occupants with the same overall seat configuration. Conventional adjustable seats utilize individual mechanical actuator units for each adjustable component. Therefore, increasing the adjustability of the seat requires additional actuators, increased weight, complexity and cost. Contents of the invention [0003] In one embodiment of a pneumatically adjustable seat, the seat includes: a seat frame having a seat back frame portion; and a head restraint coupled to the seat back frame portion. The headrest includes elastic pads. The driver assembly includes a contact member operatively connected to the resilient pad. A bladder is operably coupled to the contact member and is in fluid communication wi...
