Abstract
A seat adjustment and locking mechanism employs a pedestal permanently affixed to the deck and having a bore on its top frame member to engage a through bolt. The bolt supports a pin pad with a multiplicity of small pins on its top surface. A seat frame bottom wall containing a slot moves around the bolt and pin pad. A panel containing small holes is located within the seat frame. In a relaxed position the panel rests on the pin pad and causes engagement of the pins with the holes on the bottom surface of the panel to secure the seat in a locked position.
Claims14
A seat adjustment and locking mechanism comprising:
- (a) a seat supporting stationary pedestal having a bore through a top frame member,
- (b) a seat frame mounted over the pedestal,
- (c) the seat frame having a bottom wall provided with an opening over the pedestal bore, front and back walls and a top wall,
- (d) a pin pad having a diameter larger than the width of the opening in the bottom wall, the pin pad juxtaposed to a shaft, the shaft protruding downwardly through the opening in the bottom wall and the pedestal bore, the shaft being affixed to the pedestal at an end distal from the pin pad,
- (e) a substantially planar panel having a top and bottom surface, the panel positioned between the bottom and top seat frame walls, the panel hinged at a first end to the front wall and at a second end to the back wall of the seat frame, the panel being bendable at a midsection,
- (f) a multiplicity of holes on at least one grating affixed to the bottom surface of the panel to receive corresponding pins from a top surface of the pin pad, and
- (g) means for lifting the panel to retract the holes on the grating from the pins so that the seat frame is movable within the dimensions of the opening in the bottom wall.
A seat adjustment and locking mechanism comprising:
- (a) a seat frame supporting stationary member affixed to the deck of an aircraft,
- (b) a seat frame having a bottom wall provided with an opening, a front and back side wall and top wall,
- (c) a shaft mounted at a first end to the seat supporting member and at a second end to a pin pad above the bottom wall, the pin pad having a diameter greater than at least one dimension of the central opening,
- (d) a panel having a top and bottom surface mounted between the top and bottom wall of the seat frame by hinging at a first end to the front wall and at a second end to the back wall, the panel being liftable at about a midpoint between the first and second end,
- (e) a multiplicity of apertures on the bottom surface of the panel receiving a corresponding multiplicity of upright pins located on a top surface of the pin pad when the panel is substantially planar to lock the seat frame in a fixed position, and
- (f) means for lifting the panel at its midpoint.
