Abstract A sliding block for adjustably mounting e.g. an ear cup at a protective helmet or a head clamp having a U-shaped carrier includes a base member and a channel-shaped cover. The base member includes a prismatic head and a shaft projecting therefrom, and a passage extends through the head and the shaft. Grooves are provided at two mutually opposite sides at the head for receiving the shanks of the carrier. In mounted position the cover will enclose the head and lock the shanks in the grooves, however permitting a sliding movement of the block along the carrier. The cover has an internal projection snapping into the mouth of the passage at the head, and the opposite mouth of the passage is provided with tongues for engaging a stud on the ear cup.
A sliding block for movably supporting a component on a U-shaped carrier having parallel shanks and comprising a base member having a head and a shaft projecting therefrom, said head being including a least two parallel, laterally spaced side walls arranged at a distance mainly corresponding to the distance between the shanks of said U-shaped carrier, a groove in each of said side walls frictionally receiving one of said shanks, and a channel-shaped cover which grippingly encloses said head and said side walls whereby said block is frictionally supported by said carrier.
