Title: Safety device for motor-cycle - flings rider upwards and forwards in event of collision
Inventor: GYOERY KALMAN PETER
IPC: B62J27/00
Filed: 1989-06-14
Abstract: The saddle of a motor-cycle has a central upper part (2) which is mounted in a metal frame (6) which is pivoted to the main part of the saddle at its front end (7). In the event of a collision with an obstacle, a device (20-53) under the upper part (2) tends to move forwards relative to the saddle (1). This movement releases a bolt (6) which holds the central upper part (2) to the main part (1). The upper part (2) has a weight (5) embedded in its rear end. When the bolt (60) is released, this weight causes the upper part (2) of the saddle to swing upwards and forwards, flinging the rider clear of the obstacle. USE - Motor-cycle safety.
