Abstract: An actuator release mechanism includes: a longitudinal sleeve movable along an axis between a lock and release positions; drive means for causing the longitudinal sleeve to move along the axis; and bias means to bias the longitudinal sleeve to the lock position. The drive means includes: a rotary solenoid having a first direction of rotation and a second direction of rotation; a toggle member having a toggle shaft connected to and rotatable with the rotary solenoid, and a toggle head in engagement with the longitudinal sleeve by pins extending radially inwards from the longitudinal sleeve and a helical guide rail provided on a radially outer surface of the toggle head. The longitudinal sleeve is mounted around the toggle head, such that rotation of the solenoid causes rotation of the toggle member and the guide rails which causes the pin(s) to ride along the guide rail to rotate the sleeve.

Abstract: An actuator release mechanism comprising a longitudinal member, e.g. a piston, which is moveable axially to permit or prevent axial movement of the lock bolt and hence deployment of the actuator. Movement of the piston is due to the force of the lock bolt, under a spring force, on the one hand, and to the position and force of a linkage assembly on the other hand. The linkage assembly comprises a first link fixed, at one end, e.g. by means of a piston lock pin, to the piston and fixed at a pivot point to a second link. The second link is fixed to a rotational drive means, here a rotary solenoid or stepper motor, so as to rotate about a centre of rotation.

Abstract: A release mechanism comprises a locking body mounted for reciprocating movement in a first axial direction between a locked position and a released position. A force transmitting element is coupled to the locking body for transmitting a force (F) to the locking body for moving the locking body from the locked position to the released position. A biasing element acts on the locking body in a direction for moving the locking body from the released position to the locked position. The locking body comprises a slot having a first slot portion extending in said first direction, and a second slot portion extending transversely from one side of said first slot portion at an end thereof. The slot slidably receives an actuating element therein.
