A parking brake assembly which includes a brake lever, a rotary clutch and a lock-release mechanism which cooperate to selectively lock and release a parking brake. The clutch allows actuation of the brake lever in one direction and prevents movement of the brake lever in an opposite direction. The lock-release mechanism allows selective movement of the rotary clutch and the brake lever together in the opposite direction. A gear mechanism is operatively coupled between the brake lever and the rotary clutch.

A pedal system includes a support base; a first lever that is pivotally mounted to the support base; a second lever that is pivotally mounted to the support base; a first pedal coupled to the first lever and configured to be engaged by a foot of a user to rotate the first lever: a second pedal coupled to the second lever and configured to be engaged by a foot of the user to rotate the second lever, and an adjustment assembly configured to adjust a default rotational orientation, about an axis of rotation, of the first and the second lever, the first and the second lever positioned at the default orientation when no external force is applied to the first and the second lever.

A foot pedal for a medical device for placement on a working surface of a medical operatory includes a housing defining a reference plane; a cord having a first end coupled to the housing and a second end configured to be coupled to the medical device; and an actuator coupled to the housing and configured to be actuated by a user to provide a control function to the medical device, wherein the housing includes a self-leveling mechanism for urging the placement of the foot pedal on the working surface in an upright orientation. The self-leveling mechanism may include an engagement tab extending from the housing and configured to be the first aspect of the foot pedal to contact the working surface. The self-leveling mechanism may additionally or alternatively include a cord guide configured to pitch or cant the housing in a preferential direction.

A pedal operation amount detection apparatus for an operation pedal apparatus that includes a transmitting member including a pedal arm of an operation pedal that is disposed to be pivotable about a support axis and subjected to a depressing operation, and an output member to which a depressing operation force is transmitted from the transmitting member and to which a reaction force corresponding to the depressing operation force is applied, the pedal operation amount detection apparatus includes a sensor member disposed on a load transmission path of the transmitting member and the reaction force and the pedal operation amount detection apparatus electrically detects deformation of the sensor member. The sensor member is an elongate member that is torsionally and elastically deformable about a torsion center line in a longitudinal direction and is disposed at a position offset from the transmitting member in a direction parallel to the support axis.

According to one embodiment, a method of adjusting an aircraft pedal assembly includes providing a pedal linkage coupled between a pedal and an attachment assembly situated proximate to an aircraft instrument panel. A brake cylinder is provided coupled between the pedal and the attachment assembly. The pedal linkage is rotated in response to an adjustment input. The pedal linkage is maintained approximately parallel to the brake cylinder during rotation of the pedal linkage.

A brake pedal assembly includes an assembly frame, a pedal arm pivotally carried by the assembly frame, a booster input rod, a booster washer carried by the booster input rod, a rod actuating element carried by the pedal arm and engaging the booster input rod and a biasing device interposed between the booster washer and the rod actuating element.

A vehicle brake assembly includes an actuation lever coupled to a brake pedal. The brake assembly also includes a push rod of a brake booster. The push rod has a clevis on an end portion thereof. The clevis comprises two prongs. The brake assembly further includes an alignment device seated on each respective prong of the clevis. The alignment devices are configured to collectively guide and position the clevis into alignment with the actuation lever during construction of the brake assembly.

An alignment device may include a saddle element configured to sit on a pedal arm of a brake assembly. The saddle element may include first and second U-shaped ends configured to receive the pedal arm. The first and second U-shaped ends may be spaced apart from one another by an opening defined by first and second lateral wing elements. The first and second lateral wing elements may form a catchment area configured to guide and position a push rod of a brake booster into alignment with the pedal arm.

An automatic throttle for a hydrostatic transmission having a forward pedal and a reverse pedal. Each pedal actuates a swash plate on a hydraulic pump for forward and reverse travel. A first bell crank and a second bell crank are connected to the forward pedal and the reverse pedal respectively. Each bell crank may pull a Bowden cable connected to an engine throttle to increase engine speed when either of the pedals is depressed.
