Abstract
Chair having seat and back parts capable of springy tilting relative to each other. The seat and back parts are provided in the region where they join each other with a reduced width to intensify the relative tilting thereof. Longitudinal slots are also provided in the seat and extend from the region of reduced width to further intensify this relative tilting. The chair frame is provided with fastening elements in the region of the front edge of the seat for tilting attachment of seat and back.
Claims14
In a chair having a seat part integrally joined to a back part and defining a one-piece bucket seat with a flexible bending region at the location of joining of the seat and back parts, said bucket seat being attached to a chair frame support structure, the improvement comprising:
- (a) the bending region of the bucket seat has a width as measured from opposite sides of the seat and back parts thereof;
- (b) the seat part includes longitudinal slots extending from the opposite sides of the bending region toward the front thereof;
- and
- (c) the area of the seat and back parts located laterally between the slots is of continuous solid construction.
In a chair having a frame provided with fastening elements in the region of the front edge of the seat part for tilting attachment of seat and back parts, the seat and back parts being capable of moving springily toward and away from one another, the improvement wherein:
- (a) the seat part and back part are a one-piece integral structural element joined together centrally of the sides thereof with the width of the seat and back parts being reduced in the transition region between seat and back in relation to the width of the remaining portions of the seat and back parts for intensifying springy displaceability between seat and back parts;
- and
- (b) the seat part is firmly fixed only at the front end thereof so the seat and back parts as a unit are capable of springy swinging about the front edge of the seat.
In a chair having a frame provided with fastening elements in the region of the front edge of the seat part for tilting attachment of seat and back parts, the seat and back parts being capable of moving springily toward and away from one another, the improvement wherein:
- (a) the seat part and back part are a one-piece integral structural element;
- (b) the seat part is firmly fixed only at the front end thereof so that seat and back parts as a unit are capable of springy swinging about the front edge of the seat;
- (c) the chair frame includes a vertically disposed telescopic part for adjustably supporting the seat part at different heights;
- and
- (d) a forklike fastening element is attached to the upper end of the telescopic part and includes at least two prongs extending to the front end of the seat part and attached thereto.
