Claim:
A restraint system equipped with a rotatable shoulder holder to increase survival chance in a real-world accident of a vehicle, train or an aeroplane or in an inflight turbulence, comprising a seat belt ( 1 d , 1 e ), consisting of several belt portions, at least one latch plate, a lap buckle assembly ( 9 . 1 ), a belt pretensioner and belt fittings; the rotatable shoulder holder ( 10 d ), having a pair of shoulder caps ( 10 . 2 d ), which, when in a resting position, are located in a seat backrest ( 3 . 2 d , 3 . 2 e ); and a rotatable device ( 28 ), having a pair of rotatable levers ( 28 . 5 ), retained by stop pieces ( 28 . 9 ) in the resting position, where the rotatable levers ( 28 . 5 ), having first ends, connected to the pair of shoulder caps ( 10 . 2 d ), and second ends, connected to each other by a shaft ( 28 . 7 ), are rotatably attached to a pair of casings ( 29 ), each of which, defined by an L-shaped plate ( 28 . 4 ) and two outer tubes ( 28 . 1 , 28 . 2 ), connected to each other by a coupling wall ( 28 . 3 ), is height-adjustable, latchable and guided by inner tubes ( 71 , 72 ) of a seat backrest frame ( 3 . 4 d , 3 . 4 e ); wherein a passenger is restrained by the seat belt ( 1 d , 1 e ) and his shoulders are restrained by the shoulder caps ( 10 . 2 d ), moved by the rotatable device, when operated from the resting position to an operative position; where at least one shoulder belt portion of the seat belt ( 1 d , 1 e ) is extended over the respective shoulder cap and a U-shaped plate ( 10 . 15 ) thereof, when the rotatable levers ( 28 . 5 ) are rotated, causing release cams ( 28 . 6 ) of the rotatable levers to force a rotation of lock pawls ( 28 . 8 ), pre-loaded by first springs ( 28 . 10 ), thereby permitting locking pins ( 28 . 12 ), pre-loaded by second springs ( 28 . 13 ) and loosely guided in guide tubes ( 28 . 11 ), to move into holes ( 28 . 14 ) of the casings ( 29 ) and block the rotatable levers in both directions.
