Abstract

A frame-type chair includes a frame having a base subframe and a back subframe. A seat is mounted on the base by sockets formed in the seat which receive frame ends in heat-stake and telescopic relationships. A back is mounted on the back subframe and includes sockets which receive back subframe ends in heat-stake relationships. The chair can be provided with a pair of arms or with a tablet arm.

A chair comprising:

(a) a frame including a base subframe and a back subframe;
(b) said base subframe including a pair of base subframe sides each having:
(1) front and back legs;
(2) upper and lower longitudinal members;
(3) said back leg being connected to said upper horizontal member at an upper rear corner;
(4) said front leg being connected to said lower horizontal member at a lower front corner;
(5) said back leg being connected to said lower horizontal member at a lower rear corner;
(6) said front leg terminating at an upper end;
and
(7) said upper longitudinal member terminating at an upper longitudinal member end positioned in spaced relation from said front leg upper end;
(c) said back subframe having:
(1) a pair of back support members each having an upper end;
(2) a pair of back subframe extension members each connected to a back support member at a respective back support/extension member corner, each having a front end and each being positioned in parallel, adjacent relation to a respective upper longitudinal member and welded thereto on an inside of said upper longitudinal member, each of said back subframe extension member ends being positioned in spaced relation rearwardly from a respective upper longitudinal member end;
and
(3) a back subframe crosspiece extending between and connected to said extension members at said support/extension member corners;

(6) a first pair of sockets in proximity to said seat opposite sides respectively;
(7) a second pair of sockets in proximity to said seat opposite sides respectively;
(8) said first pair of sockets each including a receiver receiving a respective front leg upper end in a heat stake relationship therein;
and
(9) said second pair of sockets each including a receiver slidably receiving a respective upper horizontal member end and each engaging a respective back subframe extension member end;
and
(e) a back including:
(1) a front face;
(2) a rear face;
(3) an upper edge;
(4) a lower edge;
(5) opposite sides;
and
(6) a third pair of sockets extending rearwardly from said back rear face and each including a receiver receiving a respective back support member upper end in a heat stake relationship therein.
