In an adjustable seating system, allowing variation in the spacing between adjacent rows of passenger seats, e.g. in an aircraft, for use in a passenger vehicle, each row (14, 16, 18) is mounted on a longitudinal seat rail (30) secured to the floor. The seat rail (30) has a series of equally spaced
In an adjustable seating system, allowing variation in the spacing between adjacent rows of passenger seats, e.g. in an aircraft, for use in a passenger vehicle, each row (14, 16, 18) is mounted on a longitudinal seat rail (30) secured to the floor. The seat rail (30) has a series of equally spaced openings (34) along its length for retaining the seating units (14, 16, 18) at any selected lengthwise location. Alternate rows (16) have seat adjustment means comprising a plunger (60, 144) for engaging in said rail (30) mounted for vertical movement between a rail-engaging position in which it engages with the rail (30) to restrain fore and aft movement and a release position in which it permits fore and aft movement of the seating unit (16), a foot (84, 156) for engaging in said rail (30) so as to resist both fore and aft movement and vertical movement, a lever (86, 158) pivotally mounted on the foot (84, 156) and having a cam follower (88, 160) engaging in vertically extending guide means (90, 162) secured to the seating unit (16), and coupling means (64, 132) responsive to displacement of the cam follower (88, 160) from the bottom of the guide means (90, 162) to move the plunger (60, 144) to its release position and adapted to return the plunger (60, 144) to its engaged position when the cam follower (88, 160) returns to the bottom of the guide means (90, 162).

An adjustable seating system, for use in a passenger vehicle, comprising a floor-mounted seat rail adapted to extend longitudinally through at least a portion of a passenger carrying compartment and at least three seating units mounted on said seat rail; the seat rail including a series of equally spaced interconnected openings along the length of said rail for fixedly engaging and retaining the seating units at any selected lengthwise location; at least one of the seating units including seat adjustment means comprising: a first plunger for engaging in said rail mounted on a leg of said seating unit for vertical movement between a rail-engaging position in which said plunger engages with the rail to restrain fore and aft movement and a release position in which said first plunger permits fore and aft movement of the seating unit, a second plunger for engaging in said rail so as to resist both fore and aft movement and vertical movement, a lever pivotally mounted on the second plunger, vertically extending guide means secured to the at least one seating unit, a cam follower secured to said lever and engaging in said vertically extending guide means so as to be positionable at the bottom of the guide means either when the seating unit is in a first position in which the lever projects forwardly from the second plunger or when the seating unit is in a second position in which the lever projects rearwardly from the second plunger, the distance between these two positions being a multiple of the spacing between the opening in the rail so that the plunger can move into an engaged position when the seating unit is in either of these two positions, and coupling means responsive to displacement of the cam follower from the bottom of the guide means to move the first plunger to the release position and adapted to return the first plunger to the rail-engaging position when the cam follower returns to the bottom of the guide means.
