Description

Seat cushion inclination adjustment mechanism

technical field

The utility model relates to an automobile seat, in particular to an inclination adjustment mechanism of a seat cushion.

Background technique

Most seats (including car seats and truck seats) are realized by a four-bar linkage mechanism plus a locking mechanism, and the structure is complex.

The seat cushion adjustment mechanism in the existing truck seat is limited by the four-bar linkage mechanism, and there are limitations such as a limited adjustment angle, a lock mechanism limited by the supplier, insufficient adjustment gears, and a large space occupation.

The inclination adjustment of the seat cushion in the existing car seat is mainly realized by electric adjustment, and the cost is relatively high.

Contents of the invention

The purpose of the utility model is to provide a seat cushion inclination adjustment mechanism.

The utility model includes a seat cushion, a seat cushion side plate, a frame and a locking device. The seat cushion is hinged on the frame through a hinge shaft. The plate is provided with locking holes arranged up and down. Two locking devices are welded on the frame. The locking bolt of the locking device can be inserted into the locking hole of the locking tooth plate to lock. out of the locking hole of the plate to unlock.

The locking device is composed of a body, a lock bolt, a return spring, a gate wire and a cover plate. The body has a chute, the lock bolt is located in the chute, the head of the chute has a limiter, and the body below the chute It has a bar-shaped groove, and the tail of the bar-shaped groove has a rib. The return spring is located in the bar-shaped groove. One end of the return spring is pressed against the rib, and the other end of the return spring is pressed against the lock bolt. The core wire is connected, the leather wire of the brake wire is fixed on the body, and the cover plate is fixed on the body.

The working principle of the locking device: Under normal conditions, the locking bolt protrudes under the support of the return spring, and the locking bolt is inserted into the locking hole of the locking tooth plate. When the brake line is pulled, the locking bolt is pulled inward and shrinks. Back, the lock bolt comes out of the locking hole of the locking tooth plate.

Working principle and process of the utility model:

When the locking bolt of the locking device is released from the locking hole of the locking tooth plate and unlocked, at this time, the seat cushion is adjusted to a suitable angle by the occupant, and then the brake line is released, and the locking bolt of the locking device is inserted into the lock. Lock in the locking hole of the tooth plate, and then adjust the comfortable riding angle.

The beneficial effects of the utility model:

1. Simple structure: Compared with the seat without seat cushion inclination angle adjustment function, this utility model only adds seat cushion side panels and locking mechanisms, and does not require redundant connecting rods and synchronous connecting rods;

2. Strong applicability: only need to weld the locking mechanism between the side panel of the cushion and the frame to adjust the inclination angle, and can be applied to various truck seats and car seats.

3. Large adjustment range: the utility model can realize the angle change in the upper and lower directions of the seat cushion, and the adjustment range is large, and the adjustment range can be changed by changing the size of the locking tooth plate according to the customer's requirements.

4. Accurate adjustment: there is one locking point every 2° on average, and the adjustment step can also be changed according to different needs.

5. Various ways of unlocking the handle: the unlocking handle is connected to the unlocking mechanism through the gate line, so the position of the handle and the direction of unlocking the handle can be adjusted arbitrarily.

6. During the adjustment process, the angle of the seat cushion and the backrest changes together to improve the comfort of the seat.

detailed description

As shown in Fig. 1, Fig. 2 and Fig. 3, the present embodiment includes a cushion 1, a cushion side plate 2, a frame 3 and a locking device 4, the cushion 1 is hinged on the frame 3 through a hinge shaft 5, and the seat cushion 1 Cushion side plates 2 are arranged on the inner side, and the seat cushion side plates 2 are provided with locking tooth plates 21, and the locking tooth plates 21 are provided with locking holes 22 arranged up and down, and two locking devices 4 are welded on the frame 3 to lock The locking bolt 42 of the device 4 can be inserted into the locking hole 22 of the locking tooth plate 21 to lock, and the locking bolt 42 of the locking device 4 is released from the locking hole 22 of the locking tooth plate 21 to unlock.

As shown in Figures 4, 5 and 6, the locking device 4 is composed of a body 41, a lock bolt 42, a return spring 43, a brake wire 44 and a cover plate 45, the body 41 has a chute 411, and the lock bolt 42 is located in the chute 411, the head of the chute 411 has a limit gear 412, the body 41 below the chute 411 has a bar-shaped groove 413, the tail of the bar-shaped groove 413 has a rib 414, and the return spring 43 is located in the bar-shaped groove In 413, one end of the return spring 43 is pressed against the rib 414, and the other end of the return spring 43 is pressed against the lock bolt 42. The tail of the lock bolt 42 is connected with the core wire of the brake wire 44, and the leather wire of the brake wire 44 is fixed on the body. 41 , the cover plate 45 is fixed on the body 41 .

The working principle of the locking device 4: under normal conditions, the locking bolt 42 protrudes under the abutment of the return spring 43, and the locking bolt 42 is inserted into the locking hole 22 of the locking tooth plate 21. When the brake wire 44 is pulled, the The locking bolt 42 is pulled inward to retract, and the locking bolt 42 escapes from the locking hole 22 of the locking tooth plate 21 .
