Abstract: A bumper mounting assembly comprises a support member mountable to a vehicle front and a bumper-carrying member hingedly mounted to the support member to be movable between an upright position and a lowered position. A primary actuator is secured to the support member and the bumper-carrying member and can apply braking force against movement of the bumper-carrying member from the upright position to the lowered position and can preferably move the bumper-carrying member from the lowered position to the upright position. One of the bumper-carrying member and the support member carries a detent and the other carries a movable latch and a latch actuator for moving the latch between an engagement position and a disengagement position, with the latch biased into the engagement position so that the latch can selectively retain the bumper-carrying member in the upright position. A system to maintain pressure in a spare tire is also described.
