A roll bar assembly capable of punching through a rear window ( 12 ) on deployment comprises a deployable u-shaped roll bar ( 1 ) fitted with a pin ( 4 ) made of hard material. An item of trim ( 5 ) is located over the top of the roll bar ( 1 ) by means of a pair of spring clips ( 7,8 ). The clips are held under tension so that when the bar is deployed, they snap snugly around the bar, releasing stored energy which assists in the bar's deployment. The trim ( 5 ) is further provided with an orifice ( 6 ) through which the pin can protrude on the deployment of the bar thereby enabling the pin ( 4 ) to contact the rear window ( 12 ) and to shatter the glass.
