Abstract: A mechanical sensor comprises a casing having an axis, an inertia body received in the casing for displacement axially thereof, and an output member received in the casing for displacement axially thereof and having a portion extending out of the casing so as to transmit displacement of the output member to the outside of the casing. A set spring biases the inertia body to a set position in the casing. A stopper is received for axial displacement within the casing, and an actuator spring is engaged between the inertia body and the stopper and is also engageable with the output member to cause it to displace upon displacement of the stopper. Latch members movably coupled to the inertia body are engaged between the stopper and the casing in the absence of displacement of the inertia body in response to a predetermined acceleration of the inertia body so that the stopper stores energy in the actuator spring.

Abstract: A self-locking safety belt reeling device comprising a reeling arbor disposed in a belt housing is further provided with a spring housing attached to the belt housing. A return spring and a shock-absorbing spring are arranged inside the spring housing whereby the return spring has a greater spring force than he shock-absorbing spring. A coupling wheel with a wheel shaft is rotatable supported inside the spring housing for coupling the return spring to the shock-absorbing spring such that, in a first operational state, the return spring and the shock-absorbing spring together function as a reeling spring, and, in a second operational state, only the shock-absorbing spring functions as the reeling spring. The coupling wheel is actuatable as a function of a reeling state of the safety belt. A rotational oil damper with a spindle is connected to the spring housing and the spindle is fixedly connected to the wheel shaft of the coupling wheel to prevent sudden shock during the reeling process.

Abstract: A seat belt for a pilot seat or flight attendant seat in an aircraft includes a belt tightener with a reversible energy storage member in the form of a helical compression spring and a rod-shaped energy converter coupled to the energy storage member. The energy converter is at least indirectly connected to a belt member of the seat belt. After the belt member has been tightened and the energy converter has been displaced as a result with an at least partial regeneration of the energy storage member, a cutting chisel penetrates the surface of the energy converter and dampens the movement of the belt member. A renewed activation of the energy storage member after the deceleration phase is prevented by the penetration of a clamping edge of a clamping member in the surface of the energy converter.

Outside said housing, no electrical leads are required, resulting in an extensive shielding from electromagnetic interference signals and a high saving of costs.

Abstract: In a safety-belt system comprising a winding and locking mechanism, a clamping device is provided which carries out a clamping of the safety-belt outside the reel winding, wherein this clamping effect is caused by a lifting motion of the winding and locking mechanism or of a part thereof and is fastened by suitable means so that the load-bearing clamping organ comes to engage with its entire clamping surface on the belt and the approach of the clamping surface to the belt is synchronized. According to the invention clamping readiness of the clamping organ is begun on every vehicle deceleration of more than 0.45 g and on every belt withdrawal acceleration of more than 1.5 g. The belt winder contains, apart from the driving spring and the winding shaft, only the sensor and control mechanism, and does not require any separate locking elements in order to cause preblocking.

Abstract: In the operation of modern tactical aircraft, crew members are subjected to periodic high acceleration loads that cause fatigue and a decrease in operating capacity. Restraining the torso of a crew member and pulling the crew member back against the ejection seat (2) of the aircraft would help prevent such fatigue. Known restraint and haul back apparatus for use during ejection are not adapted for repeated in flight use. The invention provides a single mechanism that retracts torso restraint straps (6) any number of times during in flight maneuvering and also retracts straps (6) for ejection. A loop (7) of each strap (6) extends around an inflatable member (28). When in flight acceleration loads exceed a preset limit, engine bleed air inflates member (28) to expand loops (7). This retracts straps (6) and positions the crew member. Member (28) is allowed to deflate when the acceleration subsides. When the ejection procedure is initiated, a gas generator (44) inflates member (28).

Abstract: A motor vehicle seat is guided, as is customary, with its upper tracks in lower tracks and is manually adjustable and lockable into selected longitudinally spaced seat positions.

Abstract: A safety belt system, especially for vehicles. The system has a three-point safety belt, a self-locking belt winding mechanism which is mounted on a structural part of the vehicle, and a clamping mechanism for the belt. The clamping mechanism is disposed on the structural part of the vehicle, and has at least one movable clamping jaw. The problem with a basic safety belt system of this type is that in particular the slack in the belt at the body of the strapped-in person, together with the belt elongation which additionally results due to the stretching of the belt, lead, upon activation of the clamping effect, to a forward shifting of the body, thus endangering the person who is strapped in. This problem is inventively solved by movably guiding the clamping mechanism on the structural part of the vehicle, and by providing a drive or control mechanism for the movement of the clamping mechanism.

Abstract: A seatbelt clamp for locking a seatbelt to restrain a vehicle occupant and prevent elongation of the seatbelt due to tightening of loops remaining on a seatbelt retractor is provided. The clamp comprises two operation plates, adjustable relative to each other, which are slidably mounted on a base plate. The base plate has a case on its lower end housing a fixed clamping jaw and a movable clamping jaw, the latter being biased by a spring into a non-clamping position. The two plates also are normally biased by a spring into a non-clamping position. If an emergency results, which throws the passenger against the seatbelt, causing the tension in the seatbelt to exceed a predetermined level of force, the two plates are urged against the biasing force, and a cam provided on the lower end of the lower operation plate drives the movable clamping jaw into the fixed jaw to clamp the seatbelt therebetween.

Abstract: A latch housing attachable to a side wall of a vehicle frame holds a vertically movable cradle having a spring mounted sensing roller over which a loop or bight of a shoulder harness belt passes. The cradle is also spring mounted in the latch housing. The bottom portions of the facing walls of the cradle cavity in the housing converge to define a downwardly diminishing chamber into which a latch wedge fixed to the bottom of the cradle is movable by belt motion against the cradle spring force. The harness belt extends from each each end of the bight or loop to the take-up reel fixed to the vehicle and to the conventional lap belt near the lap belt buckle. The harness belt passes between the wedge faces and the adjacent faces of the Latch housing lower slanting walls so that swift momentum forces drive the wedge surfaces into binding contact with the belt runs but slower changes in belt momentum are absorbed by the roller mount springs, which are preferably adjustable.
