Description

Technical Field

[0001] The utility model relates to automobile accessories, in particular to a backrest adjustment remote end unlocking mechanism. Background Art

[0002] With the diversification of automobile functions, drivers' requirements for seat operating comfort are gradually increasing. Convenient operation and appropriate human-machine configuration can provide drivers and passengers with a comfortable driving experience.

[0003] The backrest unlocking mechanism for automotive seats is typically located on the seat side guard. When in use, the driver or passenger typically sits in the seat and adjusts the seat back using the unlocking handle on the side. Lifting the unlocking handle upward unlocks the recliner through a lever, allowing the seat back to be adjusted. In commercial vehicles, adjusting the seat back angle while in the rear berth or standing requires the driver to bend over or sit on the seat to operate the unlocking handle. This single unlocking method doesn't meet the seat back adjustment needs of berth and standing passengers.

[0004] Therefore, it is necessary to optimize the structure of the unlocking mechanism to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of the utility model is to provide a backrest adjustment remote unlocking mechanism to improve the operational convenience of backrest unlocking.

[0006] The technical solution adopted by the present invention to solve its technical problems is:

[0007] A backrest adjustment remote unlocking mechanism comprising:

[0008] An unlocking support member, which is mounted on the seat bottom via a rotating structure and can perform a deflection motion on the seat bottom;

[0009] A proximal operating member, which is mounted on the unlocking support member and can be used to operate the unlocking support member to drive it to perform a deflection action;

[0010] A deflection return member is mounted on the bottom of the seat and cooperates with the unlocking support member. The deflection return member drives the unlocking support member to return to its original position after deflection.

[0011] An angle adjustment unlocking member is located at the bottom of the seat, engages with the seat back recliner, and cooperates with the unlocking support member. When the unlocking support member deflects, it can drive the angle adjustment unlocking member to move, thereby unlocking the back recliner;

[0012] A remote unlocking member, which is mounted on the top of the seat via a rotating structure and can be deflected at the bottom of the seat;

[0013] The remote transmission component is installed in the seat and cooperates with the remote unlocking component and the unlocking support component respectively. When the remote unlocking component is deflected, the unlocking support component can be driven to deflect by the remote transmission component to unlock the backrest adjuster.

[0014] Specifically, the unlocking support member includes:

[0015] The supporting arm is installed on the bottom of the seat through a rotating shaft and can be deflected at the bottom of the seat. Its operating end extends toward the front of the seat, and its matching end extends toward the angle adjustment unlocking component.

[0016] The proximal operating components include:

[0017] A proximal handle is installed at the operating end of the support arm and extends toward the front of the seat. The proximal handle can be used to drive the support arm to deflect.

[0018] The deflection return component includes:

[0019] A return spring, one end of which is mounted on the bottom of the seat and the other end of which is engaged with the mating end of the support arm, drives the support arm to return to its original position after deflection.

[0020] The angle adjustment unlocking component includes:

[0021] An unlocking plate, one end of which is engaged with the backrest angle adjuster, and the other end of which is in contact with the matching end of the support arm. The deflection of the support arm drives the unlocking plate to deflect, thereby unlocking the backrest angle adjuster.

[0022] The remote unlocking member includes:

[0023] The remote handle is installed on the top of the seat through a rotating shaft and can be deflected on the top of the seat.

[0024] The distal transmission components include:

[0025] A mounting frame, which is fixed to the bottom of the seat and corresponds to the position of the supporting arm;

[0026] The transmission cable is arranged in the seat, the bottom end of which passes through the mounting frame and engages with the matching end of the support arm, and the top end engages with the remote handle. When the remote handle deflects, the support arm can be driven to deflect through the transmission cable.

[0027] The advantages of the present invention are:

[0028] The unlocking mechanism is provided with a proximal operating component and a distal unlocking component, which the user can operate at the front and rear ends of the seat, making the backrest angle adjustment more convenient. Through the setting of the distal transmission component, remote control from the top to the bottom of the seat can be achieved, which increases the flexibility of the seat function. The deflection of the distal handle can be effectively transmitted to the supporting arm through the transmission cable to achieve the unlocking of the backrest adjuster. Commercial vehicle drivers can also adjust the seat back in the berth position or when standing, thereby improving the passability of people. BRIEF DESCRIPTION OF THE DRAWINGS
