Abstract
Description
The present invention relates to a recliner for a seat having minimized clearance between parts during locking operation of the recliner and increased rigidity.
The seat of the vehicle usually includes a seat back that supports the back of a passenger, and a seat cushion that supports the thigh from the hips.
Seatbacks can be adjusted in angle with recliners, which require convenient adjustments to achieve optimum driving posture, maintain seatback angle after adjustment, and strength to protect passengers in the event of a collision .
In recent years, recliner, which is a core component of a seat, has been attracting much attention for weight reduction due to the recent trend of light weight for improving the fuel efficiency of automobiles. However, there is a problem that weakness is caused in strength and clearance.
Fig. 1 is a view showing a conventional recliner in which a
In the case of such a conventional recliner, when the cam 4 rotates when the
However, in the conventional recliner, when the external gear of the lock gear is engaged with the internal gear of the gear rim, the lock gear supporting member supported by the cam pushes the lock gear only in the radial direction, The clearance between the outer teeth of the gear rim and the gear teeth in the gear rim is reduced but the clearance between the side surface of the lock gear and the guide block for guiding the clearance is not reduced.
In addition, since the space in which the lock gear support member is to be rotated and the space in which the lock gear is to be linearly moved must be necessarily secured in the recliner, the overall size of the recliner must be increased. There is also a growing problem.
Further, since a lock gear supporting member for pushing the lock gear in conjunction with the rotation of the cam is added, the parts to be actuated in locking and unlocking are extended, so that the inter-part operation is not smooth and the behavior of each part is incomplete, There is also a problem that half locking may occur.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the conventional problems as described above, and it is an object of the present invention to improve the locking performance of a part rotating with a seat back, minimize a clearance between parts in a locking operation of a recliner, To provide a recliner.
According to an aspect of the present invention, there is provided a portable terminal comprising: a lower part rotatably provided with a shaft and formed with a guide block; An upper part provided to be relatively rotatable with respect to the lower part and the shaft; A lock member which is moved along the guide block when the shaft rotates and is locked or unlocked on the inner peripheral surface of the upper part; And a sub-lock member which is moved during rotation of the shaft and presses one end of the lock member to move the other end of the lock member to come in close contact with the guide block.
The upper part is rotated in a concentric manner with the lower part; The guide block is formed on one surface of the lower part along the circumferential direction; Wherein the lock member is provided between the guide blocks and is slidingly moved in the radial direction about the shaft; The sub-lock member is provided between the lock members and can slide in the radial direction about the shaft.
One end of the lock member is formed with an inclined surface, and the inclined surface may have an outer end portion inclined toward the outer end portion of the sub-lock member.
A pressing sloped surface having a slope corresponding to the sloped surface may be formed at an end of the sub-lock member for pressing the lock member.
A guide block is provided on both sides of one end of the sub-lock member, and the sub-lock member is guided along the guide block; A pressing portion is formed on both sides of the other end of the sub-lock member such that when the sub-lock member moves in the outer radial direction, the pressing portion presses the one end of the lock member.
An inner tooth is formed on an inner peripheral surface of the upper part; A main external tooth is formed on the outer surface of the locking member facing the internal teeth; A sub external tooth is formed on an outer surface of the sub-lock member facing the internal teeth, and the main body and the sub external teeth are engaged with the internal teeth so that the upper part can be locked.
A shaft penetrating through the center of the lower part and the upper part and being relatively rotatable; A guide member formed on one surface of the lock member and the sub-lock member; And a cam hole is formed in a portion corresponding to the guide projection so as to have a length that gradually changes from the center of the shaft so that the guide projection is guided along the cam hole while rotating, And an actuating plate for linearly moving the movable plate in the radial direction.
A step portion formed on the inner surface of the lock member and the sub-lock member facing the shaft, respectively; A cam plate rotatable in association with the shaft and provided with a support portion on an outer circumferential surface corresponding to the step portion so as to limit or allow radial movement of the lock member and the sub-lock member when the support portion is supported or disengaged from the step portion during rotation; .
The pressing portion of the sub-lock member for pressing and supporting the lock member can be configured to support the lock member with at least the same or stronger force than the support portion that supports the lock member.
And a restoring spring for providing an elastic restoring force with respect to the rotational operating direction of the actuating plate for unlocking the lock member and the sub-lock member from the upper part.
The lower part is connected to the seat cushion; The upper part being connected to the seat back and rotatably coupled to the lower part; The cam plate is disposed on one side of the lower part between the shaft and the locking member and the sub-locking member; An actuation plate is provided between the cam plate and the upper part; The restoring spring is once hooked to the lower part and the other end is configured to be hooked through the cam plate and the actuating plate; The shaft may be provided through the upper part, the actuating plate, the cam plate and the lower part.
According to the present invention, since the end portion of the sub-lock member presses the lock member by the inclined surface structure so that the lock member is brought into close contact with the guide block, the clearance is removed between the lock member and the guide block , The locking structure of the recliner is designed to be robust and the assembling rigidity of the recliner is increased.
Further, since the sub-lock member is provided between the lock members, a space in the radial direction is not required in the recliner for movement of the sub-lock member, and the recliner can be made smaller and lighter, .
