    摘要： A tilt system for tilting a power wheelchair seat comprises a seat frame having laterally extending front and rear cross tubes and side tubes. A rear cross plate extends laterally between the wheelchair side frames and is slidably engageable with the side frames. A pivotal connection is provided between the rear seat cross tube and the rear cross plate. A front actuator cross tube is supported at a front end of the wheelchair base. A linear actuator is supported between the rear cross plate and the front actuator cross tube. A tilt linkage is disposed along opposite sides of the seat frame. Each tilt linkage has a front end pivotally connected to the wheelchair base and a rear end pivotally connected one of the side tubes of the seat frame. Another embodiment of the invention includes a glide system is secured to the inner surfaces of the wheelchair side frames. Another embodiment of the invention includes a wheelchair having a base comprises of two side frames. A glide system attached to the inside surface of each side frame. Another embodiment of the invention includes an adjustable pivot boss that is attachable to the side frames of a wheelchair so as to extend substantially perpendicularly from the side frames. A tilt linkage sleeve is pivotally engageable with the pivot boss. Both the pivot boss and the tilt linkage sleeve have co-axial central axes. The pivot boss is rotatably adjustable so as to change the location of axes.

    摘要： A method of operating a wheelchair during an un-recline process involves a wheelchair having tilt and recline functions, the wheelchair including a seat frame, a tilt actuator for tilting the seat frame, a back frame, a recline actuator for reclining the back frame. A sensor for determining the angle of recline is provided. A controller for controlling the tilt actuator and recline actuator is also provided. The controller is provided with a plurality of preprogrammed sequences for moving the seat frame and the back frame during an unrecline procedure. The sequences include tilting the seat frame as an initial part of the unrecline sequence, wherein the sequences are a function of the initial angle of recline at the initiation of the recline sequence. An initial angle of recline at the initiation of a recline sequence is determined, and the back frame is unreclined according to one of the preprogrammed sequences in response to the determined initial angle of recline.

    摘要： A method of operating a wheelchair during an un-recline process, where the wheelchair includes a seat frame and a back frame, includes positioning the wheelchair user in the wheelchair with the back frame reclined, and rotating the seat frame of the wheelchair so that the seat frame and the back frame form an angle that is within the range of from about 80 degrees to about 120 degrees. The back frame is unreclined by rotating the back frame and the seat frame while maintaining the angle between the seat frame and the back frame within the range of from about 80 degrees to about 120 degrees.
