Abstract
A technician's work chair includes a frame, first, second and third air cushion devices, a seat assembly and an electronic task guiding system. The seal assembly has a cushion portion and a seatback portion. The cushion portion is supported to the seat supporting portion of the frame. The seatback portion has an inclination adjusting mechanism operable to change an angle of inclination of the seatback portion relative to the frame. The electronic task guiding system is supported to the frame, the electronic task guiding system being configured to provide the technician with task related signals.
Claims20
A technician's work chair comprising:
- a frame having a first forward leg portion, a second forward leg portion and a rearward leg portion, the frame further having, a seat supporting portion located proximate the rearward leg portion and extending at least partially over the rearward leg portion, a tool supporting portion and a hardware supporting portion installed to the frame proximate one of the first forward leg portion or the second forward leg portion, the first forward leg portion extending forward from the seat supporting portion, the second forward leg portion extending forward from the seat supporting portion such that the first forward leg portion and the second forward leg portion define an angle therebetween that is an obtuse angle α1 greater than 100 degrees;
- a first air cushion device attached to the first forward leg portion proximate a distal end thereof;
- a second air cushion device attached to the second forward leg portion proximate a distal end thereof;
- a third air cushion device attached to the rearward leg portion proximate a distal end thereof, each of the first air cushion device, the second air cushion device and the third air cushion device being spaced apart from one another and being supplied with compressed air;
- and
- a seat assembly having a cushion portion and a seatback portion, the cushion portion being attached to the seat supporting portion of the frame and the seatback portion having an inclination adjusting mechanism operable to change an angle of inclination of the seatback portion relative to the frame such that a technician seated in the seat assembly ergonomically operates tools and completes tasks with arms raised over the technician's head, the seat assembly and the frame being positioned such that a forward most portion of the cushion portion is located rearward of the first forward leg portion and the second forward leg portion, the cushion portion being cantilevered in a forward direction from the seat supporting portion of the frame;
- wherein
- the frame, the seat assembly and the air cushion assembly are dimensioned and configured such that with the technician seated in the seat assembly the technician's feet freely engage the floor surface in order to move the frame and the seat assembly using his/her feet with little or no effort due to near friction free characteristics provided by the air cushion assembly, and wherein the technician's feet engage the floor at a location that is between respective distal ends of the first forward leg portion and the second forward leg portion.
A technician's work chair comprising:
- a frame having a plurality of leg portions, a seat supporting portion, a tool supporting portion and a hardware supporting portion installed to the frame, the frame having a V-shape as viewed from above;
- a plurality of air cushion devices, each of the plurality of air cushion devices being attached to a corresponding one of the plurality of leg portions of the frame, each of the plurality of air cushion devices being supplied with compressed air;
- a seat assembly having a cushion portion and a seatback portion, the cushion portion being supported to the seat supporting portion of the frame and the seatback portion having an inclination adjusting mechanism operable to change an angle of inclination of the seatback portion relative to the frame such that a technician seated in the seat assembly ergonomically operates tools and completes tasks with arms raised over the technician's head;
- a work light attached to the seat assembly that is configured for flexible movement for aiming the work light;
- and
- at least one hardware bin fixed to the frame such that the technician can retrieve hardware or a part therefrom for installation to an underside of a vehicle,
- the plurality of air cushion portions including a first air cushion device attached to the frame at a location forward of and to a first side of the seat assembly, a second air cushion device attached to the frame at a location forward of and a second side of the seat assembly, and a third air cushion device attached to frame below the seat supporting portion below the seat assembly, each of the first air cushion device, the second air cushion device and the third air cushion device being spaced apart from one another and each being supplied with compressed air from a compressed air source, wherein
- the frame having the V-shape, the seat assembly and the plurality of air cushion devices are dimensioned and configured such that with the technician seated in the seat assembly the technician's feet freely engage the floor surface in order to move the frame and seat assembly using his/her feet with little or no effort due to near friction free characteristics provided by the plurality of air cushion devices, and wherein the technician's feet engage the floor at a location that is within a space defined by the V-shape of the frame.
A technician's work chair comprising:
- a frame having a first forward leg portion, a second forward leg portion and a rearward leg portion, the first forward leg portion and the second forward leg portion defining a V-shape as viewed from above, the frame further having, a seat supporting portion located proximate the rearward leg portion, a tool supporting portion and a hardware supporting portion installed to the frame proximate one of the first forward leg portion or the second forward leg portion, the first forward leg portion extending forward from the seat supporting portion, the second forward leg portion extending forward from the seat supporting portion and the rearward leg portion extending rearward away from the first and second forward leg portions, with a distal end of the first forward leg portion being spaced apart from a distal end of the second forward leg portion;
- a first swivel joint attached to the distal end of the first forward leg portion;
- a second swivel joint attached to the distal end of the second forward leg portion;
- a third swivel joint attached to the distal end of the rearward leg portion;
- a first air cushion device attached to first swivel joint;
- a second air cushion device attached to the second swivel joint;
- a third air cushion device attached to the third swivel joint such that each of the first, second and third air cushion devices has freedom of movement in response to movement along a non-planar surface, each of the first, second and third air cushion devices being supplied with compressed air;
- and
- a seat assembly having a cushion portion and a seatback portion, the cushion portion being attached to the seat supporting portion of the frame and the seatback portion having an inclination adjusting mechanism operable to change an angle of inclination of the seatback portion relative to the frame such that a technician seated in the seat assembly ergonomically operates tools and completes tasks with arms raised over the technician's head, the seat assembly and the frame being positioned such that a forward most portion of the cushion portion is located rearward of the first forward leg portion and the second forward leg portion such that the technician's feet freely contact the floor within a space defined between the first and second forward leg portions within the V-shape, the cushion portion being cantilevered in a forward direction from the seat supporting portion of the frame.
