An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises plurality of panels, each panel comprising a core with a top side and a bottom side. The top side has a plurality of top projections. The top projections form top side water drainage channels. The panels have edges, with the edges of one panel abutting the edges of adjacent panels, thereby forming a drainage path between adjacent panels. The panel edges have vertical support extensions that extend into the drainage paths between adjacent panels. The vertical support extensions have an upper surface for supporting an artificial turf assembly overlying the turf underlayment layer, and the panel edges having one or more complementary indentations corresponding to vertical support extensions of adjacent panels. When the panels move toward each other, thereby closing drainage paths between adjacent panels, the vertical support extensions are received in the corresponding indentations.

A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction.

A personal mobility vehicle includes an base unit having a frame and front and rear pivot arms pivotally mounted at respective front and rear pivot points. The front and rear pivot arms support casters. A drive unit having a ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. The base unit may also include a drive unit that is pivotally supported on the base unit by a torque arm and a suspension system that includes a suspension stop. The torque arm selectively disengages the suspension stop to allow movement of the front caster wheel in response to the terrain traversed.

Wheelchair seat back mounting hardware permits the seat back to be mounted on various wheelchairs. The mounting hardware may be in the form of two-point mounting hardware that connects the seat back to the wheelchair and permits the seat back height to be adjusted independently of the mounting hardware location on the wheelchair.

A wheelchair has a primary articulated member and at least one secondary articulated member, a primary sensor for detecting the position of the primary member, a secondary sensor for detecting the position of the secondary member, and a controller capable of articulating the secondary articulated member as a function of the movement of the primary articulated member.

Coordinated articulation of wheelchair members

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.

Frame member

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.
