Abstract
Abstract An automobile with a body passenger compartment open at the top has two tilting hoods located at a distance from one another, with each hood being provided with a lock that is connected by a connecting element with an operating handle of an operating device. Both hoods are unlockable from the passenger compartment. Provision is made such that both operating handles are associated with a common operating device, which comprises a bearing housing with a central cylinder lock. Molded notches on both operating handles cooperate with outside walls of the lock housing of the cylinder lock.
