  • Patent number: 7178876
    Abstract: A belt lock is provided and has a lock holder that is rotatably mounted on a vehicle part. A restoring spring, as a flat spiral spring, has spiral spring windings that are disposed in a single plane and are disposed between a cover and the lock holder. The spiral spring biases the lock holder into a rest position of the belt lock, and has one end supported against the lock holder and another end supported against the cover. The cover has a first radially extending extension for the outer end of the spring, and a second extension as a stop for restoring of the lock holder.

  • Patent number: 5090641
    Abstract: A casing for parachutes adapted to set down a load, said parachutes having a parachute canopy, shroud lines, and a carrying harness attached thereto for the load. To simplify manufacture and shorten packing time, and to make it particularly suitable for accommodating a parachute that is adapted to set down a rapidly rotating load, the casing comprises at least two substantially flat fabric sections (11, 12) arranged one above the other and joined together at their outer edges by an encircling seam (14), with one fabric section having a central opening (17).

  • Patent number: 5016534
    Abstract: In a missile for setting down a load ejected from the missile after its launch, with at least one parachute that is attached to the load being packed in a container mounted in the missile, and with the cords of the load-carrying parachute being attached to an intermediate member coupled to the load, the intention is to reduce the size of the operational parts to be transported with the missile and improve the operation thereof during the setting down process. For this purpose it is envisaged that the container should be in the form of a two-part casing having an upper part which can be sprung open, and a plate-shaped lower part having a portion fixedly connected to the load and a support disk as the intermediate member attached to cords of the parachute. The support disk is capable of being folded out from the lower part portion while remaining connected thereto by a connecting element.

  • Patent number: 4958566
    Abstract: A braking mechanism for a rotating flying object. The braking mechanism includes a planar fabric sheet having a central attachment base portion that can be secured to the flying object. The fabric sheet is adapted to be stored in a folded-up readiness state in the flying object, and, when released and unfolded, is adapted to form a braking surface that encircles the flying object. The braking mechanism further includes a plurality of reinforcing strips that each extend radially between the central attachment base portion and an outer rim of the braking mechanism and are distributed about the periphery of the latter. Each reinforcing strip extends from the central attachment base portion to the rim and back again to at least partially form two layers and to form loop-like pockets at the rim, with centrifugal weights being disposed in these pockets.
