A vehicle seating system includes a top frame for mounting to a vehicle seat. A bottom frame is provided for mounting to the vehicle and a middle frame or linking system movably mounts the top frame to the bottom frame. The middle frame includes two pair of scissor arms with rollers at the ends of the scissor arms. The top frame has four corners with roller tracks at each corner. The bottom frame also has four corners with roller tracks at each corner. Included among the roller tracks of the top and bottom frames is a single pair of curvilinear tracks, a pair of pivotal connecting tracks and two pair of linear tracks. A regulator system is also disclosed to regulate the amount of fore and aft travel of the top frame.

Vehicle seating system with improved vibration isolation

An engine control system is disclosed having a unit for providing signals indicative of the position of an engine throttle member. The unit comprises a housing assembly associated with an engine throttle member and containing a stator assembly and a rotor assembly. The rotor assembly moves relative to the stator assembly as the throttle member moves. The rotor and stator assemblies are electrically coupled together for producing first and second continuously variable, ratiometrically identical signals whose values depend upon the throttle member position. The first signal is delivered from the housing assembly for use in controlling the engine operation. Processing circuitry processes the second signal for producing a throttle position validation signal having a first value when the throttle member is in an engine idle range of positions and a second value when the throttle member moves beyond the idle range of positions. If the first signal and the validation signal signify incompatible throttle member positions the engine speed is limited to 'idle.'

Throttle position validation method and apparatus

A differential pressure transmitter, a pneumatically operated square root extracting device therefor and methods of making the same are provided, the transmitter having a rod operatively interconnecting a movable wall with a cam roller to cause the roller to roll on a flat surface as the value of the pressure in an output chamber defined by the movable wall changes, the rod and the movable wall respectively having universal joint units snap-fitted together to provide for universal movement therebetween while movement of the wall causes the roller to roll.

A manifold means adapted to detachably carry on one side thereof a plurality of pneumatically and electrically operated control units each of which is adapted to be fluidly and electrically interconnected to pneumatic means and electrical means of the manifold means by plug-in means of the units respectively cooperating with plug-in means of the pneumatic means and electrical means of the manifold means at the one side thereof. The manifold means has external interconnection means for the pneumatic means and the electrical means on the other side thereof whereby external pneumatic and electrical lines can all be interconnected to that other side of the manifold means.

Manifolding means for electrical and/or pneumatic control units and

A control device having a cap telescoped through a mounting opening in a control panel and being secured thereto by a nut threaded on the cap and disposed against one side of the panel and a fastener carried by the cap and disposed against the other side of the panel, the fastener comprising a substantially flat plate spanning the opening of the panel and having a bayonet opening passing therethrough and aligned with the opening of the panel and the cap having a bayonet portion extending completely through the bayonet opening and cooperating with the bayonet opening to lock the cap and plate together.

Control device mounting means and parts therefor

A diaphragm stack for a control device and having at least two flexible diaphragms separated by a rigid spacer and a pair of rigid outboard members with the pair of outboard members being secured together by a fastening means passing through the center of the stack. The outboard members and the spacer have interlocking means disposed inboard of the inner peripheral portions of the diaphragms and serially interlocking together in the stack to prevent rotation of the spacer and the outboard members relative to each other in their assembled relation in the stack.

Control device diaphragm stack and method of making the same

A manifold adapted to detachably carry on one side thereof a plurality of pneumatically and electrically operated control units each of which is adapted to be fluidly and electrically interconnected to pneumatic structure and electrical structure of the manifold. That one side of the manifold has external interconnecting structure for the pneumatic structure and electrical structure whereby external pneumatic and electrical lines can be interconnected to the same side of the manifold that the units are adapted to be interconnected thereto. The manifold is formed from a pair of plates secured together in stacked relation with one of the plates defining at least that part of the one side of the manifold that carries the external interconnecting structure and is adapted to detachably carry the control units.

Manifold means and system for electrical and/or pneumatic control

A manifold adapted to detachably carry on one side thereof a plurality of pneumatically and electrically operated control units each of which is adapted to be fluidly and electrically interconnected to pneumatic structure and electrical structure of the manifold. That one side of the manifold has external interconnecting structure for the pneumatic structure and electrical structure whereby external pneumatic and electrical lines can be interconnected to the same side of the manifold that the units are adapted to be interconnected thereto. The manifold is formed from a frame plate and a plurality of like manifold modules secured to the frame plate to provide a manifold unit, each manifold module having part of the pneumatic structure and the electrical structure and having one side thereof forming part of the one side of the manifold. That one side of each manifold module is adapted to carry one of the control units and has external interconnecting structure respectively for the pneumatic structure and electrical structure thereof.
