Abstract

Abstract This detachable head rest for the driver and passengers of a motor vehicle is of the type comprising one or more supports in the form of rods, each rod being fastened for example by screwing in a socket bearing on the top of the seat back upholstery. This socket engages a strap rigid with the frame structure of the back rest and comprises at its upper end a flange for engaging said upholstery and at its lower end a retaining portion carrying a pin adapted, in a given position of said socket about its axis, to clear a notch formed in the lower edge of said strap to permit the removal of the head rest when required.
