Abstract: A height adjuster (200) for a vehicle safety restraint comprising: a rail (230) for providing a vertical path guide for a carrier (220); the carrier (220) configured to be vertically movable along the rail to one of a plurality of locations, the carrier also configured to rotationally support the web guide (210). The height adjuster also comprises a lock mechanism (240) movable between a locked and an unlocked condition, when in a locked condition the carrier is prohibited from moving down the rail and when in an unlocked condition the carrier is free to be moved; and a return spring mechanism (300) comprising a coiled return spring having an interior or coiled end (372) and a distal end (376), the interior end configured not to rotate as the carrier is moved and a distal end of the return spring secured to one of the carrier and release mechanism.

Abstract: A height adjuster (100) adapted for use with a seat belt system, the height adjuster including: a lock bar (110) having a lock side (116) with optional teeth (116a) and an opposing side (118); a lock lever (120) having an opening (122) therethrough, the lock bar receivable through the opening, a portion of the lock lever proximate the opening (122) configured as a lock edge (128) engagable with the lock side of the lock bar (110), the lock lever (120) movable between a disengaged position in which the lock edge is disengaged from the lock side and an engaged position in which the lock edge is engaged with the lock side of the lock bar; a clutch and actuator assembly (200) movably mounted to the lock bar and configured to move the lock lever between the disengaged position and the engaged position upon relative movement between the assembly (200) and the lock lever (120), the assembly (200) including a clutch portion (210) and an actuator portion (202).

Abstract: A track fastener apparatus for use with a locking track of the type used to secure a seat or cargo apparatus to the floor of a vehicle. The track fastener includes at least one locking disc sized to fit in a predetermined one of the enlarged openings in the track, and mounted for movement between an unlocked position wherein the locking disc is positioned above the enlarged opening in the track and a locked position wherein the locking disc is positioned in the enlarged openings in the track and engaged by the locking segments of the locking track adjacent the enlarged openings thereby preventing movement of the track fastener along the length of the track. A vertical bore extends through the track fastener housing and communicates with the bottom side of the track fastener housing adjacent the at least one locking disc. A lock actuator is positioned in the bore and operatively connected to the locking disc for moving the locking disc between the locked and unlocked position.

Abstract: A seat leg and track fitting assembly for removably securing a seat to a generally channel-shaped track secured to the fuselage of an aircraft. The track fitting assembly includes a forged body member having a narrow finger portion; a plurality of spaced track lugs projecting laterally from the narrow finger portion, and an enlarged boss portion having a recess formed therein. The recess extends through the narrow finger portion to form a pair of shoulders adjacent opposite sides of the recess and a plunger has surfaces positioned between the shoulders such that the shoulders limit movement of the plunger. An actuating arm is secured to the plungers in each of a plurality of track fitting assemblies to move the plungers in the recesses between first positions wherein the lower ends of the plungers are positioned adjacent the lower edge of the narrow finger portion of each body and an elevated position wherein the plungers are retracted from the track.

Abstract: A microprocessor controlled battery charger to charge a battery when the charging current is reduced to zero even though the charger is still connected to the battery. The microprocessor includes a means to read the voltage of the battery and also includes a timer. The voltage of the battery is periodically read and when it decreases below a predetermined value the microprocessor again establishes recharging of the battery first at an intermediate rate until either a maximum voltage is reached or a minimum dv/dt is reached and then the current is reduced to a lower current rate for a finishing charge of the battery for a given period of time.

Abstract: A microprocessor controlled battery charger utilizes a high frequency switching circuit and a means to read the voltage of the battery plus a timer in the circuit wherein the microprocessor is connected both to the timer and to the voltage reading means and establishes a decreasing step charging rate of the battery so as to charge the battery at a first charging rate, then at a second lower charging rate until the rate of change of voltage with time is less than a small amount of volts per hour and then the current is reduced to a third charging rate for a finishing charge of the battery. In the preferred embodiment the first charging rate is maintained until a predetermined battery voltage is achieved and the third charging rate is maintained for a given period of time.
