Abstract
A seat assembly for accommodating vibrations imparted thereto including a seat having a bottom surface, a frame including a base secured to a fixed surface and a support member extending upwardly therefrom. A substantially rigid pivot member is provided which includes a forward portion and a rearward portion. The pivot member being pivotally secured to the frame at a pivot point disposed on the pivot member between the forward portion and the rearward portion, and the forward portion being pivotally secured to the seat, the pivot member permitting the seat to move relative to the fixed surface. A biasing device is included which extends between the frame and the rearward portion of the pivot member to accommodate the movement between the seat and the frame.
Claims17
A seat assembly comprising:
- a seat having a bottom surface;
- a frame including a base secured to a fixed surface and a support member extending upwardly therefrom, wherein said support member includes a pair of spaced rails disposed behind said seat;
- a guide extending between each one of said pair of spaced rails and said seat for guiding movement of said seat relative to the fixed surface;
- a substantially rigid pivot member having a forward portion and a rearward portion, said pivot member being pivotally secured to said frame at a pivot point disposed on said pivot member between said forward portion and said rearward portion, and said forward portion being pivotally secured to said seat, said pivot member permitting said seat to move relative to the fixed surface;
- and
- a biasing device extending between said frame and said rearward portion of said pivot member to accommodate the movement between said seat and said frame.
A seat assembly comprising:
- a seat including a seating surface disposed generally parallel to a fixed surface for supporting an occupant of said seat;
- a frame secured to the fixed surface;
- a rigid pivot member having a first portion rotatably secured to said frame and a second portion rotatably secured to said seat thereby permitting said seat to move relative to the fixed surface;
- an air spring;
- and
- a shock absorber, said air spring and said shock absorber being disposed behind said seating surface so as not to interfere with downward movement of said seat said air spring and said shock absorber being operatively connected to said seat and said frame to permit controlled movement of said seat relative to the fixed surface and to isolate said seat and an individual seated within from shocks imparted to the fixed surface.
A seat assembly comprising:
- a seat having a bottom surface;
- a frame including a base secured to a fixed surface and a support member extending upwardly therefrom;
- a substantially rigid pivot member having a forward portion and a rearward portion, said pivot member being pivotally secured to said frame at a pivot point disposed on said pivot member between said forward portion and said rearward portion, and said forward portion being pivotally secured to said seat, said pivot member permitting said seat to move relative to the fixed surface, said pivot member including a pair of outwardly extending rods and said base including a pair of spaced brackets having an aperture therein for receiving said pair of rods;
- and
- a biasing device extending between said frame and said rearward portion of said pivot member to accommodate the movement between said seat and said frame.
