Safety and arming unit for a spinning projectile fuze

A safety and arming unit for a spinning projectile fuze, said fuze including a fuze body (12) and a bearing body which define a hemi-spherical contact therebetween, a spherical rotor (18) being rotatably mounted in said cutout, a detonator (20) being arranged in said rotor (18), said rotor (18) possessing a recess (22) into which a bushing (24) projects in the safe position of the safety and arming unit (10) prevents the rotor (18) from rotating, the rotor (18) having at least one recess (62) into which a radially oriented transverse bolt (64) projects in an interlocking manner in the safe position of the safety and arming unit, at least one transverse bolt (64) being held in the recess (62) in the safe position by an acceleration bolt (70) and a first spring element (72), which are axially oriented, and a second spring element (76) being connected to the at least one transverse bolt (64), said rotor (18) being prevented from rotation into an axial armed position thereof until release of said bushing (24) into movement away from said rotor (18) by a second arming system.
