A button-driven unlocking protrusion moves seat brake rollers from wedge to release surfaces, simplifying operation while preventing roller tilt.
A button-driven unlocking member pushes seat brake rollers off wedge surfaces, simplifying height adjustment and preventing roller tilt.
A wedge-and-roller brake module locks free seat height-link hinges during collisions to prevent seat frame deformation and improve passenger safety.
A segmented operation bracket cuts housing contact area to reduce clutch sliding resistance while maintaining secure fastening and smoother operation.
Engagement protrusions and grooves lock the clutch outer ring to the housing without welding, avoiding distortion and extra assembly steps.
Independent clutch and brake control lets a walk-behind machine brake one wheel while powering the other for near-zero-radius turns.
Direction-dependent clutches in a coaxial drive device resolve torque detection conflicts while minimizing construction volume.
A clutch unit gear member meshes with a stationary member to lock the output shaft, preventing seat lowering under continuous reverse torque input.
Brake pedal linkage moves a fixation member to cancel auto-cruise, eliminating separate switch operations.
Circumferential cam contact points shift force distribution toward the rotation axis, reducing weight while maintaining braking stability.
