Abstract

The invention discloses a lordosis support of a seat back bracket, which comprises a support bottom plate, wherein two groups of sliding grooves are formed in the upper end and the lower end of the upper surface of the support bottom plate; sliding brackets which are connected in a sliding manner are arranged into the sliding grooves; three elastic connecting plates are welded between the upper ends of the two sliding brackets; an arc support plate is arranged on the upper surfaces of the three elastic connecting plates; a fixed support plate is welded in the middles of the three elastic connecting plates; two electric telescopic rods are in bolted connection between the lower surface of the fixed support plate and the upper surface of the support bottom plate; the electric telescopic rodsextend and contract to enable the fixed support plate to move so as to adjust a bending degree of the arc support plate; the adjustment is more convenient; the support can be fixed on a seat back viafixing brackets; and the lordosis support of the seat back bracket is simple in structure, easy and simple to operate and more convenient to mount and can be adjusted.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a lordosis support for a seat back bracket. Background technique [0002] At present, the back of the seat basically adopts a hard backboard, and then lays soft foam suitable for the curve of the human back. Long-term use of the seat will cause the foam to lose its elasticity, thereby accelerating the fatigue of the human back muscles, and more likely to cause damage or bending of the back spine. This seat needs to be installed with a lordotic support, which is generally designed with a curved back of the seat, so it cannot be adjusted during use, and the installation is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a lordotic support for the seat back bracket, which has a simple structure and is easy to operate. Not only can the support be adjusted, but also the su...
