Abstract: An adjustable lumbar support (10) adapted to be easily integrated into new or existing seat structures. Adjustable lumbar support (10) includes a floating plate (15) supported by a support linkage. In one embodiment, the support linkage is defined by a cable member (21) and first and second spring members (25) and (26) which engage the seat frame. In an alternate embodiment, the support linkage is defined by first and second spring members 25 engaged with first and second linkage members (52), respectively, and includes a rotary power mechanism (50) for applying a rotating motion to a shaft (54) threadably engaged with first and second linkage members (52). The degree of support provided by floating plate (15) is adjusted by adjusting the effective length of the support linkage. Lumbar support mechanism (10) can be mounted in a state of the art seat back alone or in conjunction with an integral trim attachment array (70).

Abstract: An adjustable lumbar support for a seat having a seat frame is disclosed, the adjustable lumbar support including a floating support plate for providing an amount of lumbar support to a lumbar region of a seat, the support plate having a front surface and a rear surface, the floating support plate being attached to the seat frame via springs, the provided lumbar support defining an apex. A first actuator assembly and a second actuator assembly are each operatively connected to the floating support plate via respective first and second cables, the first and second cables being spaced from each other substantially vertically within the floating support plate, the first and second actuator assemblies for selectively actuating the respective cables to selectively move the apex substantially vertically and substantially horizontally forward and back relative to the seat frame. A secondary support plate may be provided, and may be hingedly and/or floatingly mounted.

Abstract: An adjustable lumbar support (100) adapted to be easily integrated into new or existing seat structures. Adjustable lumbar support (100) includes a lower floating plate (115) that is adapted to have a second, or upper, plate (130) hinged relative to the lower plate (115). The upper and lower plates have independently actuated support linkages (120 and 140) that are selectively actuated by first and second actuating mechanisms. In this manner, selective actuation actuator mechanisms associated with the lower and upper support plates (115 and 130) provides adjustment of a vertical dimension of the adjustable floating plate lumbar support. The degree of support provided by floating plates (115 and 130) is adjusted by adjusting the effective length of the support linkages.

Abstract: Adaptors are disclosed for a seat assembly. The adaptors may be used for mounting a support extending substantially across a frame between first and second side members. The adaptor may be attachable to an opening in the frame. The support may include a hook having a bending distal end. The adaptor includes a non-metal body including a mounting structure configured for attaching the body to the opening in the frame, a passageway extending through the body for receiving the hook, and a seat within the body for securing the bending distal end of the hook to the adaptor. The mounting structure is configured so that when the support is loaded the adaptor is loaded by the hook substantially in compression. Alternatively, other designs with the loading in compression or tension are possible whereby the adaptor includes other combinations of features. Seat assemblies are also disclosed. The support may be a seat back or bottom, or a lumbar support. Methods of assembly are also disclosed.
