Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, a multifunctional chair includes a supporting frame 1, a seat 2 and a backrest 3, the top end of the backrest 3 is provided with a bevel extension 31, the bevel extension 31 is horizontally disposed, the bevel extension 31 corresponds to an outward inclined position 113 of a supporting rod 112 at the backrest 3 position, specifically, a vertical projection of the bevel extension 31 does not exceed the outward inclined position 113 of the supporting rod 112 at the backrest 3 position, the height of the bevel extension and the ground is in accordance with the height of the ergonomic design, and the bevel extension 31 after being stressed can still keep the center of gravity at the middle position of the supporting frame 1.

In the embodiment, the seat 2 is an inclined seating surface, and the seat 2 is inclined with a high front side and a low rear side; the backrest 3 is an inclined back surface, the upper side of the backrest 3 is inclined backwards, the lower side of the backrest 3 is inclined forwards, the seat 2 and the backrest 3 are in butt joint at the middle position of the support frame 1, so that the gravity center of the seat 2 and the backrest 3 is inclined to the center position of the support frame 1 under stress, the supporting frame 1 is composed of two supporting feet 11 which are symmetrically distributed on the two sides of the chair seat 2 and the backrest 3, the supporting leg 11 is composed of a horizontal connecting rod 111 and two supporting rods 112, and during the manufacturing process, a horizontal connecting rod 111 and two supporting rods 112 of the supporting foot 11 can be bent and formed integrally by steel, horizontal connecting rod 111's length is greater than the vertical projection of seat support 2 and back 3, two bracing piece 112 one ends are installed respectively on horizontal connecting rod 111's both ends, and the other end is installed respectively at the front side of seat support 2 and the upside position of back 3, makes two bracing pieces 112 be outer eight characters inclined support seat support 2 and back 3 from top to bottom. Therefore, when in use, the supporting rod 112 is inclined outwards from top to bottom, so as to increase the stress surface for supporting the chair seat 2 and the bevel extending part 31 thereof, and the stress center of gravity is in the middle position of the supporting frame 1, so that the reliability and stability of the chair seat are improved, and the chair seat is not easy to overturn.
