Abstract: An automatic braking safety belt retractor reel includes a reel provided with a first ratchet reel rotatable with a shaft and spring biased in a belt retracting direction. A braking pawl is movable into engagement with the ratchet reel by a rockable second ratchet wheel which is advanced by a second pawl pivoted on an inertial wheel and urged into engagement with the ratchet wheel by a cam on the shaft when the inertial wheel lags the rotation of the cam as a result of the rapid shaft acceleration. An armature of magnetic material is mounted on a second pawl and an electromagnet having an annular core, when excited, attracts the armature to prevent the engagement of the second ratchet wheel by the second pawl and the braking of the reel. The electromagnet is excited upon occupation of the seat or closing of the vehicle door and is de-excited upon buckling of the belt.

Abstract: An automatic locking safety belt rewind reel includes a U-shaped bracket supporting a shaft to which is affixed a spring rewound reel having a ratchet wheel end plate and a rockable ratchet wheel locking first pawl is spring biased out of engagement with the ratchet wheel. An internally toothed second ratchet wheel rockably mounted on the shaft is coupled to the first pawl. Carried by the shaft within the internal ratchet wheel is an inertia wheel carrying a second pawl and a cam wheel so related that rapid acceleration of the shaft causes a lag in the inertia wheel rotation, actuation of the two pawls and locking of the reel. In order to permit free unwinding of the reel, a frustoconical annular retractor member is axially movable toward and away from the path of a follower on the second pawl to respectively free and restrain the pawl in its disengaged position and the retractor member is spring biased to its retracted position and solenoid actuated to its advanced pawl retracting position.

Abstract: A unitary woven composite tube and web includes a tubular section and an interwoven web section which may be formed as a tube, and which is useful for inflatable safety belts and other uses. The composite article is woven wherein the filling runs are successively interwoven with the longitudinal warps along an upper forward first run, a lower return second run below the first run, a third forward run extending to and interweaving the second run at a point intermediate its ends and a return fourth run and the cycle is repeated. Various warp filling weaves may be employed. The tubular section may house a longitudinally extending cable. The filling and warp may be interwoven in any desired pattern.

Abstract: An automatic locking vehicle safety belt retractor includes a shaft on which is affixed a belt take up reel having similar first ratchet wheels at its opposite ends. A spring retracted transverse pawl member includes pawl teeth which are rockable with the pawl member into and out of braking engagement with the ratchet wheels and the pawl member is drive coupled to an internally toothed second ratchet wheel rockably mounted on the shaft. A fly wheel is freely rotatable on the shaft within the second ratchet reel and carries a spring retracted second pawl swingable into engagement with the second ratchet wheel and a cam wheel is rotatable with the shaft and engages a cam follower on the second pawl to advance the second pawl upon rotation of the cam wheel relative to the fly wheel.
