Abstract: A vehicle safety restraint device having an improved lock and release mechanism. The vehicle safety restraint device comprises an airbag and projectable lap plate attached to rotatably mounted transverse tubes containing compressed gas or chemical inflator cartridges, all of which are housed within a container capable of being used as a visor when in an inoperative condition. An electrical impulse from an impact sensing or emergency hand switch releases the unit to rotate into a vertical position, simultaneously inflating the airbag through telescoping tubes within the bag and projecting the lap plate into the occupant's lap. The improved lock and release mechanism, which includes one or more electrically responsive explosive wire cutters and a looped locking wire, provides rapid rotation of the airbag and transverse tube. The looped locking wire holds the spring biased transverse tube in a ready position until a signal activates the wire cutters which sever the wire, thereby releasing the tube for rotation.

Abstract: A safety clamp appliance is disclosed formed of a cable or rope housing having opposed walls and a generally U-shaped cross-section, the housing interior being adapted to receive a safety rope, and a brake lever having a pivot point, a brake surface and a handle for attachment to a workman's belt. The brake lever is pivotally mounted in the housing. An actuating spring is provided for spring loading the brake lever, thereby maintaining a constant pressure by the brake surface on the rope. The actuating spring is provided with a quick release for converting the safety clamp appliance from a spring loaded mode to a non-spring loaded mode.

The permanent necktie knot and the necktie body may be formed from a single strip of material or the knot and body may be formed from separate strips of material. In the former case, the knot is formed by folding one end of the strip material back onto the front face of the body and then folding the free ends of the folded-back portion around the body and fastening them together at the rear face. In the latter case, the knot is formed by folding one end of the body strip material back onto the rear face of the body and then encircling the knot strip material around the folded-back portion and fastening together the ends of the knot strip material at the rear face.
