A seating system has a tiltable seat coupled to a base, which can be coupled to a motor vehicle or other device. The seat includes a seat bracket coupled to the base by a seat tilt pivot. The seat is configured to maintain a user's body in a fixed position during tilting throughout the seat's range of tilt angles. A seat adjustment mechanism allows angular adjustment of the seat and locks the seat at a fixed tilt angle relative to the base. The seat tilt pivot axis is located approximately vertically below the center of gravity of a loaded seat, thus reducing the force needed to tilt a loaded seat. By fixing or maintaining the seat tilt pivot vertically beneath the load being pivoted, the amount of force needed to control seat tilting can be limited to forces that a typical user can exert with one or two hands.

A motor brake can be coupled to the rotatable motor drive shaft. The brake includes a shaft-mountable support that rotates uniformly with the drive shaft. One or more brake shoes, which can include flyweights or the like, are hingedly mounted to the support and include brake pads. A centripetal force is applied to the brake shoes using one or more springs or other biasing means that bias the brake pads against a braking surface when rotation of the shaft is below a minimum rotational velocity. The brake pads disengage from the braking surface when shaft rotation exceeds the minimum rotational velocity. The centrifugal force induced and applied to the brake shoes and brake pads by rotation of the motor drive shaft overcomes the biasing force to disengage the brake pads from the braking surface, which may be the housing of a motor to which the brake is affixed.
