Abstract

The invention provides a seat leg support adjusting mechanism. An upper connecting plate is rotationally connected with a lower connecting plate through a fixed shaft fixed to the upper connecting plate. The fixed shaft is fixedly connected with a large coil spring. The outer end of the large coil spring is hooked to a pin fixed to the lower connecting plate. One end of the upper connecting plate is provided with convex locking teeth. A toothed plate is rotationally connected with the lower connecting plate through a hinge pin. The upper side edge of the toothed plate is provided with concave locking teeth capable of being engaged with the convex locking teeth. The lower side edge of the toothed plate is provided with a front blocking edge and a rear oblique edge. An unlocking cam is rotationally connected with the lower connecting plate through a rotary shaft. A handle is fixedly connected with one end of the rotary shaft. A shifting fork is arranged at the upper end of the unlocking cam. One side of the shifting fork can abut against the front blocking edge so as to rotate the toothed plate, so that the toothed plate is disengaged from the convex locking teeth. The other side of the shifting fork can squeeze the rear oblique edge so that the concave locking teeth can be clamped into the convex locking teeth. A convex hook is arranged at the lower end of the unlocking cam. A small coil spring is connected to the lower connecting plate through a fixed pin. The outer end of the small coil spring is buckled to the convex hook. The seat leg support adjusting mechanism is simple, convenient to use, flexible, reliable and especially suitable for seat leg support devices.

Description

[0001] Technical field: [0002] The invention relates to the technical field of seat structures, in particular to an adjustment technology for seat leg rests. [0003] Background technique: [0004] Today's car seat leg support devices are being popularized and applied on various passenger cars, especially luxury cars. This device can provide support for the legs of the occupants, relieve the discomfort of riding, and has a great effect on improving the comfort of the legs of the seat. good help. But most of the seat leg support devices of the prior art adopt four-bar linkage, gas spring mechanism, or leading screw, worm gear transmission adjustment, so that the structure is heavy and complicated, and the effect is also unsatisfactory. [0005] For example, Chinese Patent No. ZL 201420426123.7, a utility model patent titled "Vehicle Seat Leg Rest Adjustment Mechanism", discloses a seat leg rest adjustment mechanism, which includes a lower block fixedly connected to the seat p...
