These members define an angle which changes as the chair is adjusted, and the arm rest member includes stop means forwardly of the support member and below the top surface, the stop means being adapted to come into contact with the support member when the angle enlarges to a predetermined size less than 180.degree.. This prevents the arm rest and support members from reaching a dead center position, and avoids the risk that the user's finger will become trapped between the support member and the forward end of the arm rest member.Type: GrantFiled: September 29, 1980Date of Patent: December 20, 1983Inventor: James A.

Patent number: 4252371Abstract: There is provided a lounge chair with a seat portion and a back portion pivotally hinged to the seat portion. Two arm rest members are pivoted to the side edges of the back portion at intermediate locations, and a U-shaped support is provided for the forward ends of the arm rest members. The U-shaped support has a base member extending between two parallel upstanding side members, and the tops of the side members are pivoted to the arm rest members. The side members are further pivoted to the seat portion at intermediate locations, such that the base member is located in spaced arrangement under the seat portion. However, the U-shaped support is disposed such that its base member remains always clear of the ground, regardless of the attitude of the U-shaped support.Type: GrantFiled: May 3, 1979Date of Patent: February 24, 1981Inventor: James A.

Patent number: 4072341Abstract: An adjustable chair as a seat, a backrest pivoted on the seat for movement between an erect and an reclined position, and a leg rest mounted on the seat for movement between a retracted and an extended position. The seat is mounted on lateral portions of a frame for pivoting so that the angular position of the backrest relative to the frame may be changed either by pivoting the backrest relative to the seat, or by pivoting the seat relative to the frame. A damping arrangement damps the movement of the backrest relative to the frame at least between some of the angular positions of the backrest, and an arresting arrangement including interengaging teeth is accommodated in an armrest pivoted on the backrest, which arrangement permits arresting the backrest in a selected one of the angular positions thereof.Type: GrantFiled: December 1, 1975Date of Patent: February 7, 1978Assignee: Kurz GmbHInventor: Rudolf Kurz
