Abstract:
1. A lumbar support with an integrated actuator housing and pressure surface comprising: an arching pressure surface having an upper region and a lower region; a first actuator housing integrally fixed to one of said upper region or said lower region of said arching pressure surface; motorized actuator disposed within said first actuator housing; a first fraction element having a first portion and a second portion, said first portion being in communication with one of said upper region or said lower region of said arching pressure surface, said second portion being in communication with said actuator such that tension on said first fraction element exerted though said first actuator housing draws said upper region and said lower region of said arching pressure surface toward one another to form an arch; a second actuator housing attached to said arching pressure surface; a second actuator disposed within said second actuator housing; a guide in supporting sliding engagement with said arching pressure surface; a second traction element having a first portion and a second portion; said first portion of said second traction element being adapted to be anchored off of said arching pressure surface; and said second portion of said second traction element being engaged with said arching pressure surface via said second actuator; such that tension on said second traction element moves said arching pressure surface from a first position to a second position, said first position and said second position being substantially along said guide.
