The patent relates to the technical field of vehicle seats, in particular to a pneumatic high-lift damping seat, which comprises a seat body, a mounting bottom plate and a height adjusting
assembly. The height adjusting
assembly comprises an inner cylinder, an outer cylinder, a
gas spring, an unlocking
handle, a cable, a locking pin, a
locking plate, a fixing plate and a support plate. The
gas spring is fixed inside the inner cylinder and the outer cylinder. The fixing plate is fixedly connected with the top of the
gas spring. The support plate is fixed at the bottom of the inner cylinder. The unlocking
handle is rotationally connected with the fixing plate. The locking pin is slidingly connected with the support plate. The
locking plate is fixed on the inner wall of the outer cylinder. The locking pin can be inserted into the
locking plate through the inner cylinder. The two ends of the cable are respectively connected with the unlocking
handle and the locking pin. The unlocking handle is linked with the locking pin through the cable. The height of the seat body can be adjusted by pressing or releasing the pressure, so that the height of the seat body can be adjusted in a
large range and quickly. The problem that the height adjusting range of the existing vehicle seat is small and not suitable for special vehicle seats is solved.
