Abstract

The utility model discloses a vehicle seat foot plate with a self-locking mechanism. The vehicle seat foot plate with the self-locking mechanism comprises a fixed beam, a jib arm, a corbel, a pedal, a lock rod, a spring, a manual connecting rod, a handle and a torsional spring. The pedal is fixed on the corbel, the jib arm is fixed on the fixed beam, the corbel is connected to the lower end of the jib arm in hinged mode through a shaft, the shaft is provided with the torsional spring in sleeved mode, the torsional spring applies force to the corbel, and the lock rod is movably inserted in a slotting hole of the jib arm and a slotting hole of the corbel. The bottom end of the lock rod is in a bevel structure, the upper end of the lock rod is connected with the manual connecting rod in hinged mode through a connecting rod, the manual connecting rod is arranged on the fixed beam, the handle of the manual connecting rod is located on the side front end of the fixed beam, bottom ends of two springs are hooked on the jib arm, and upper ends of the two springs are hooked on the lock rod. When the spring pulls the lock rod downwards, the jib arm and the corbel keep locking states. The vehicle seat foot plate with the self-locking mechanism is installed on the vehicle seats and has the advantages of being small in installation space, achieving self-locking in use and being convenient to unlock.

Description

Automotive seat stretcher with self-locking mechanism

Technical field

The utility model relates to a kind of stretcher of automotive seat, particularly a kind of automotive seat stretcher with self-locking mechanism.

Background technology

When long-distance riding in an automobile, keep for a long time a kind of attitude of taking, can cause occupant leg and foot's nervous system and blood circulation system to suffer oppression, produce sense of fatigue and sense of discomfort.Change the attitude of leg and pin, can significantly alleviate this fatigue and discomfort.Increasing stretcher in the automotive seat bottom is one of effective ways of realizing this function.

Common stretcher is that stretcher is fixing on the seat, by rotating shaft, realizes simply turnover.This type stretcher, when closed, the unitarity during for maintenance and back of seat or seat cushion motion needs additionally to increase on the seat lockable mechanism and carries out locking; During use, need to rely on feet of passengers strength that it is stopped, or rely on its gravity that it is ridden on the floor, without latch functions.Thereby cause the larger installing space of stretcher and operating effort.

Summary of the invention

The purpose of this utility model provides a kind of automotive seat stretcher with self-locking mechanism, and the utility model is installed on the automotive seat, and installing space is little, and self-locking can realize using the time, and release is easy.

The utility model is by fixed cross beam, cantilever, trailing arm, pedal, locking bar, spring, manual link, handle and torsion spring form, pedal is fixed on the trailing arm, cantilever is fixed on the fixed cross beam, trailing arm is hinged on the cantilever lower end with axle, sheathed torsion spring on the axle, torsion spring forces in trailing arm, the locking bar activity is plugged in the jack of cantilever and in the jack of trailing arm, the bottom of locking bar is the inclined-plane, pass through rod hinge connection together between the upper end of locking bar and the manual link, manual link is arranged in the fixed cross beam, the handle of manual link is positioned at the side front end of fixed cross beam, and the bottom of two springs is hooked on the cantilever, on the upper end hook locking bar of two springs, spring pulls down locking bar, makes cantilever and trailing arm be in lockup state.

Working process of the present utility model and principle are:

1, pedal is in when launching quiescence: locking bar is plugged in cantilever and the trailing arm under the effect of spring, makes trailing arm and pedal be in deployed condition, and pedal is the level of state, and puts for the foot-operated of people.

2, in the time of pedal will being drawn in: pull handle with hand, manual link drives on the locking bar and carries, and breaks away from locking between trailing arm and the cantilever, and trailing arm and pedal draw under the effect of torsion spring automatically.

3, when wish is launched pedal: press pedal and trailing arm with the underfooting, trailing arm sways, because the lower end of locking bar is the inclined-plane, locking bar can slide in the jack of trailing arm, with cantilever and trailing arm locking, is deployed condition.

The beneficial effects of the utility model: the utility model is installed on the automotive seat, and installing space is little, and self-locking can realize using the time, and release is easy.

The specific embodiment

See also Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the present embodiment is by fixed cross beam 1, cantilever 2, trailing arm 3, pedal 4, locking bar 5, spring 6, manual link 7, handle 8 and torsion spring 9 form, pedal 4 is fixed on the trailing arm 3, cantilever 2 is fixed on the fixed cross beam 1, trailing arm 3 is hinged on cantilever 2 lower ends with axle 10, sheathed torsion spring 9 on the axle 10, torsion spring 9 forces in trailing arm 3, locking bar 5 activities are plugged in the jack 21 of cantilever 2 and in the jack 31 of trailing arm 3, the bottom of locking bar 5 is inclined-plane 51, hinged by connecting rod 52 between the upper end of locking bar 5 and the manual link 7, manual link 7 is arranged in the fixed cross beam 1, and the handle 8 of manual link 7 is positioned at the side front end of fixed cross beam 1, the bottom of two springs 6 is hooked on the cantilever 2, on the upper end hook locking bar 5 of two springs 6, spring 6 pulls down locking bar 5, makes cantilever 2 and trailing arm 3 be in lockup state.

During use, the utility model is fixed on the front portion of automotive seat, and fixed cross beam 1 is fixed on the seat.

Working process of the present utility model and principle are:

1, pedal is in when launching quiescence: as depicted in figs. 1 and 2, locking bar 5 is plugged in cantilever 2 and the trailing arm 3 under the effect of spring 6, makes trailing arm 3 and pedal 4 be in deployed condition, and pedal 4 is the level of state, and puts for the foot-operated of people.

2, in the time of pedal will being drawn in: pull handle 8 with hand, manual link 7 drives on the locking bar 5 to be carried, and breaks away from locking between trailing arm 3 and the cantilever 2, and trailing arm 3 and pedal 4 draw under the effect of torsion spring 9 automatically, are Fig. 3 and rounding state shown in Figure 4.

3, when wish is launched pedal: press pedal 4 and trailing arm 3 with the underfooting, trailing arm 3 rotates around axle 10, because the lower end of locking bar 5 is inclined-plane 51, locking bar 5 can slide in the jack 31 of trailing arm 3, with cantilever 2 and trailing arm 3 lockings, is deployed condition illustrated in figures 1 and 2.
