<p>A vehicle has a vehicle body and a vehicle bonnet assembly. The vehicle bonnet assembly includes a bonnet (14) hinged at its front to the vehicle body (10) and latched at its rear by two latch devices. Each latch device comprises a latch assembly (17) mounted to the vehicle body (10) and a striker (21) mounted to the bonnet (14). Impact sensors are configured to detect a front collision with a pedestrian and two lift actuators (18) are arranged to raise the rear edge of the bonnet (14) into a deployed position in response to a pedestrian impact. Each latch assembly (17) includes a latch claw (26) moveable between a latch position in which the striker (21) is held by the latch claw (26) and a release position in which the striker (21) is releasable from the latch claw (26). Each latch assembly (17) also includes a release member (27) which is operable by a driver of the vehicle to allow the latch claw (26) to be moved towards its release position and allow the bonnet (14) to be lifted. A release actuator (32) is arranged to move the release member (27) and allow the latch claw (26) to be moved towards its release position and retain it in said position when the bonnet (14) is lifted by the lift actuators (18) in the event of a pedestrian impact. Each release actuators (32) is retained by a spring clip (37) which is attached to one end of a release tape (38) whose other end is connected to one of the lift actuators (18). The release tape (38) is normally hidden by the bodywork under the bonnet (14). However, when the bonnet (14) is moved to the deployed position by the lift actuators (18), the tape (38) is exposed and can be pulled to release the clip (37). The release actuator (32) can then pull away, allowing the latch assembly (17) to be re-set.</p> |
