    Abstract: A brake device for braking rotation of an input shaft includes a selectively operable trigger brake that includes: a static element; a trigger brake shaft mounted for rotational and axial movement relative to the static element and the input shaft; a preloaded torsion spring rotationally coupled to the input shaft but permitting a limited rotational movement between the trigger brake shaft and the input shaft; a roller jamming mechanism operable upon the relative rotation between the trigger brake shaft and the input shaft exceeding a predetermined amount to stop rotation of the input shaft upon operation of the trigger brake; and a brake actuator for selectively moving the trigger brake shaft into and out of engagement with a contact surface of the static element. Engagement of the contact surface of the static element and the trigger brake shaft overcomes the preload of the torsion spring.

    Abstract: A pumping device for a seat of a vehicle is proposed. In the pumping device, a plurality of pressure members is provided along an outer circumferential surface of a brake drum, and braking operation is performed through the pressure members moved when the brake drum rotates, so that friction between the brake drum and a housing can be avoided and thus deterioration of operational performance is prevented. In addition, the shape of the brake drum is simplified and the number of components is reduced, so that weight and size of the pumping device, and production cost are reduced, and fuel efficiency increases.

    Abstract: A medical device support system including a central shaft, an extension arm, and a brake assembly. The extension arm has a support for a medical device and a hub at its proximal end mounted to the central shaft for pivotable movement about the central shaft. The brake assembly is secured in the hub for rotation therewith and includes first and second discrete arc shape clamp pieces configured to flex toward and away from each other to respectively increase and decrease a frictional braking force to the central shaft. The hub includes a hub access opening configured to allow passage therethrough of at least one of the arc shape clamp pieces.

    Abstract: A load sensor to be used in an electromechanical brake system includes a flange member capable of deflecting when receiving, at a load receiving portion, a load from the axially front side; a support member capable of supporting the flange member from the axially rear side, at a support portion displaced from the load receiving portion in a radial direction orthogonal to the axial direction; and a displacement detecting mechanism configured to detect the amount of relative movement between the flange and support members. A variable detection sensitivity mechanism enables the relative movement amount with respect to the change of the load applied to the flange member to be larger in a low load range in which the load is equal to or lower than a predetermined load value than in a high load range in which the load is higher than the predetermined load value.
