The invention discloses an automobile seat lumbar switch valve. The automobile seat lumbar switch valve comprises a shell, an air source admission piece, an air inlet plug, an air inlet reset part, anair outlet plug, an air outlet reset part and a control assembly; the shell is provided with a shell cavity, the air source admission piece is in communication with the air inlet cavity, and the airinlet plug is used for enabling the air inlet cavity and the shell cavity to communicate with each other and cut off by sliding; the air inlet reset part is used for controlling the air inlet plug andkeeping the air inlet cavity and the shell cavity in a cut-off state, the air outlet plug is used for communicating and cutting off an air outlet cavity and the shell cavity by sliding, and the air outlet reset part is used for controlling the air outlet plug and keeping the air outlet cavity and the shell cavity in a cut-off state; and the control assembly is used for controlling sliding of theair inlet plug and the air outlet plug so that the air inlet cavity communicates with the shell cavity and the air outlet cavity communicates with the shell cavity. The automobile seat lumbar switch valve realizes the inflation and deflation of a lumbar support air bag, the function of high-pressure deflation of the lumbar support air bag is realized, so that a traditional lumbar support switch and an overflow valve are integrated together, the cost is reduced, and the arrangement space is reduced.
Description
technical field [0001] The invention relates to the technical field of car seats, and more specifically, relates to a lumbar support switch valve of a car seat. Background technique [0002] With the development of science and technology in the field of vehicle transportation, people have higher and higher requirements for vehicle ride comfort. The pneumatic support device for the lower back of the seat came into being, effectively solving the problem of human lower back fatigue easily caused by long-time driving. [0003] Usually, for passenger cars without body air source, the seat back is pneumatically supported, and a micro air pump is used as the power source to blow the air through the relevant control valve body and into the lumbar support airbags placed behind the foam cushion of the seat back respectively. Through the inflation and deflation of the airbag body, the seat surface of the backrest seat is partially raised or flattened, thereby realizing the support eff...
