Abstract: One aspect is an inertial lock friction hinge, including a shaft assembly having a shaft assembly recess and a friction assembly having a friction assembly recess. The shaft assembly and the friction assembly are rotatably coupled for relative frictional rotation. The hinge includes a restraining component positioned within the hinge such that when the hinge is in an unlocked condition the restraining component is not engaged with both the friction assembly recess and the shaft assembly recess so that the shaft assembly and the friction assembly are allowed to rotate relative to each. The restraining component is positioned such that when the inertial lock friction hinge is in a locked condition the restraining component is at least partially engaged with both the friction assembly recess and the shaft assembly recess so that the shaft assembly and the friction assembly are locked and prevented from relative rotation by the restraining component.

Abstract: One aspect is a wrap spring clutch with a rotatable input and a spring having a first and a second end and having an equilibrium state and a flexed state, the spring engaged with the input through one of the first and second ends such that the spring rotates with the input and with an input torque transmitted exclusively through one of the first and second ends when the input rotates. A damper mechanism is engaged with one of the first and second ends such that the damper mechanism causes the spring to change from its equilibrium to its flexed state when the input transitions from stationary to rotational, and such that the damper mechanism allows the spring to change from its flexed to its equilibrium state when the input transitions from rotational to stationary. A rotatable output is positioned relative to the spring such that the output synchronously rotates with the input when the spring is in its flexed state and rotates independently of the input when the spring is in its equilibrium state.

Abstract: One aspect is an insert molded torsion bar hinge including a cylindrical metal torsion bar with a main bar body, a portion of which extends along a torsion bar axis, a first contoured bar end and a second contoured bar end on opposite ends of the main bar body. A first hinged element of molded plastic and with a first knuckle, is molded directly over and encompasses the first contoured bar end such that the first contoured bar end is fixed within and not rotatable relative to the first hinged element. The first knuckle is molded directly over and encompassing a portion of the main bar body. A second hinged element of molded plastic and with a second knuckle is molded directly over and encompasses the second contoured bar end such that the second contoured bar end is fixed within and not rotatable relative to the second hinged element. The second knuckle is molded directly over and encompassing a portion of the main bar body. The first and second hinged elements rotate and produce a torsional spring torque.

Abstract: One aspect is a detent hinge device having a first cam component with at least one spline and an axial cam face, the first cam component having a root diameter and an outer diameter. A second cam component has at least one spline and an axial cam face, the second cam component having a root diameter and an outer diameter. Each of the first and second cam components are aligned on an axis, wherein the cam faces of the first inner and first outer cam components face each other. An axial spring acts on the first cam component forcing it against the second cam component. An axial retention element securing each of the first and second cam components and axial spring on the axis. A first mounting bracket has splines on an inner surface. The first mounting bracket contains the first cam component such that the splines of the first mounting bracket engage the splines of the first cam component thereby transferring torque from the first cam component to the first mounting bracket via the splines. A second mounting bracket has splines on an inner surface. The second mounting bracket contains the second cam component such that the splines of the second mounting bracket engage the splines of the second cam component thereby transferring torque from the second cam component to the second mounting bracket via the splines. The first and second cam components comprise the same shape.
