Abstract
An ergonomic weight support device for a seat has a weight distribution surface attached to a traction arching lumbar support. The weight distribution surface is only attached at the apex of the arch of the arching pressure surface. The upper and lower ends of the weight distribution surface are free to flex between a passenger's spine and the arch, distributing the passenger's weight for greater comfort.
Claims24
An ergonomic support comprising:
- at least one guide rail adapted to be mounted in a seat;
- an archable pressure surface having an upper end and a lower end, said upper end and said lower end of said archable pressure surface being movably attached to said at least one guide rail and at least one of said upper end and said lower end being disposed to slide along said at least one guide rail;
- a traction element engaged to slide said at least one of said upper end and said lower end of said archable pressure surface along said at least one guide rail such that an arch forms in said archable pressure surface, said arch having an apex;
- and
- a weight distribution surface fixed to said archable pressure surface.
A method of ergonomic weight support distribution comprising:
- mounting an archable pressure surface to a guide element at an upper end and a lower end of said archable pressure surface, said guide element being adapted to be mounted in a seat;
- engaging a traction element with said archable pressure surface such that at least one of said upper end and said lower end of said archable pressure surface, travels along said guide element to selectively arch said archable pressure surface;
- fixing a weight distribution surface to said archable pressure surface.
A method of retrofitting a weight distribution device to an ergonomic support device comprising:
- fixing a weight distribution surface to an archable pressure surface.
An ergonomic support comprising:
- at least one guide rail adapted to be mounted in a seat;
- an archable pressure surface having an upper end and a lower end,
- means for movably attaching said upper end and said lower end of said archable pressure surface to said at least one guide rail such that at least one of said upper end and said lower end of said archable pressure surface slide along said at least one guide rail;
- traction means to slide said at least one of said upper end and said lower end of said archable pressure surface along said at least one guide rail such that an arch forms in said archable pressure surface, said arch having an apex;
- a weight distribution surface;
- and
- means to fix said weight distribution surface to said archable pressure surface.
