Worker support apparatus

A support apparatus for selectively supporting a worker in one of a plurality of positions, the apparatus comprising:

• a support structure including a pair of walls which are spaced from one another in the horizontal direction and which include opposing vertical wall surfaces;
• a seat assembly including a frame, a seat and a back support member, the seat and back support member being mounted on the frame for movement with the frame;
• seat assembly positioning means for permitting movement of the frame relative to the support assembly along an upright arcuate path to selectively position the seat assembly in one of a plurality of positions relative to the support structure,
• a first pair of the plurality of rollers being rotatably mounted on one of the opposing vertical wall surfaces and another pair of the plurality of rollers being rotatably mounted on another of the opposing wall surfaces, the frame of the seat assembly including a first arcuate guide track for engaging the first pair of rollers and a second arcuate guide track for engaging the second pair of rollers;
• and
• back support positioning means for permitting pivotal movement of the back support member relative to the frame to selectively position the back support member in one of a plurality of positions relative to the seat.

A low-profile support apparatus for selectively supporting a worker in one of a plurality of positions ranging between a substantially horizontal supine position and an upright seated position, the apparatus comprising;

• a support structure;
• a seat assembly including a frame, a seat and a back support member, the seat and back support member being mounted on the frame for movement therewith;
• seat assembly positioning means for permitting movement of the seat assembly relative to the support structure along an upright arcuate path to selectively position the seat assembly in one of a plurality of positions relative to the support structure;
• the seat assembly positioning means including an arcuate guide track which defines the arcuate path and which is provided on one of the frame and support structure, and a plurality of rollers rotatably supported on the other of the frame and support structure, the rollers engaging the guide track to support the seat assembly on the support structure and being movable relative to the guide track to permit movement of the seat assembly relative to the support structure;
• back support positioning means for permitting pivotal movement of the back support member relative to the frame to selectively position the back support member in one of a plurality of positions relative to the seat,
• the seat assembly positioning means and the back support positioning means together enabling support of a worker in any one of a plurality of positions ranging between a substantially horizontal supine position and an upright seated position.

• and
• support structure locking means for selectively locking the support structure in one of a plurality of positions relative to a floor on which the apparatus is supported, the locking means including at least one brake mounted on the support structure and including a handle, the brake being selectively movable into and out of engagement with the floor.
