Abstract
Abstract 369,079. Head - rests. MITCHELL, T. W., Brussels, Ontario, Canada. May 28, 1931, No. 15580. [Class 52 (ii).] An adjustable head-rest comprises a telescopic element provided between the pad and the stock and consisting of an outer member slidably mounted in the stock and an inner member secured to the pad, teeth being provided on both the inner and outer members together with click and pawl means on the stock for engaging said teeth. Such a device is shown in the drawings, comprising a pad 14, stock 15, and two telescopic elements. Each telescopic element comprises an inner member 25 on the pad, and an outer tubular member 26 slidable within the stock. The members 25, 26 are toothed at 30, 31 and the teeth 31 are longitudinally interrupted by a slot so that the stepped clicks 34 can engage both sets of teeth. The clicks are pressed outwards by the spring 35 and can be withdrawn by pressure upon the button 39. The teeth 31 are made deeper than the teeth 30 so that the member 26 cannot be withdrawn until the member 25 has been withdrawn to its extreme position.
