<p>A haptic alert system is disclosed which is arranged to impart a vibratory motion to the back rest of a vehicle seat. The mechanism supports the back of a seat in a motor vehicle and comprises at least one first component (2,3) which is adapted to be connected to the squab of a seat, and at least one further component (32) which is adapted to be connected to the back of the seat. The components (2,3,32) are connected together by a connection arrangement. The connection arrangement is configured to permit the further component (32) to pivot relative to the first component (2,3) and an actuator arrangement (53) is provided which is configured to move the further component (32) pivotally relative to the first component (2,3) in an oscillating manner in order to impart a vibrating alert to the back rest.</p> |
