Description

[Detailed Description of the Invention] <<Technical Field of the Invention>> The present invention relates to a locking device for a foldable seat, and particularly to a connection structure between a lock lever and a lock knob.

≪Prior art and its problems≫ The tilting of the seat back in a folding seat is
Generally, as shown in FIGS. 3 and 4, by lifting up the lock knob 3 connected to the lock lever 2 extending from the locking means A, the lock from the vehicle body is released and the seat back 1 is tilted forward or backward. let

The lock lever 2 and the lock knob 3 are connected by fitting the tip of the lock lever 2 into a groove 4 formed in the lock knob 3, and tightening and fixing by inserting a bolt 5 into this fitting part.

By the way, since the size of the seat back 1 and the position where the locking means A is disposed differ depending on the vehicle model, conventionally, by changing the length of the locking lever 2 connected to the locking means A, the position of the locking means A and the locking means A are different. The lock knob 3 is shared. In other words, the protrusion length L1 of the lock knob 3 that protrudes from the top of the seat back 1 is almost constant depending on the vehicle model, but the dimension from the tip of the lock knob 3 to the locking means A varies depending on the vehicle model. Lock levers 2 of different lengths are made in advance, and a lock knob 2 of a predetermined length is selected and used depending on the vehicle type. For this reason, lock levers 2 must be manufactured and managed for each vehicle type, which is extremely troublesome.

<<Purpose of the invention>> The present invention was devised in view of the above-mentioned circumstances, and an object of the present invention is to enable the lock knob to be shared regardless of the size of the seat bag or the mounting position of the locking means.

<<Structure of the invention>> In order to achieve the above object, the present invention forms a plurality of lever mounting holes vertically in the lower end of the lock knob, selects one of the lever mounting holes, and bolts the lock lever and the lock knob. It is characterized by being made to do.

<<Description of Embodiments>> Fig. 1 is an exploded perspective view showing a locking device for a foldable rear seat to which the present invention is applied, Fig. 2A is a front view showing the locking device applied to a small seat bag, FIG. 2B is a front view showing the locking device applied to a large seat bag.

In the figure, the locking device includes a locking means 10 having a latch 10a inside a housing 10b that engages a striker (not shown) fixed to the vehicle body.
The lock lever 11 generally includes a lock lever 11 whose one end abuts against the latch 10a and whose other end extends outward from the housing 10b, and a lock knob 12 connected to the lock lever 11.

The upper end of the lock lever 11 is a fitting part 11a for attachment to the lock knob 12, and a bolt insertion hole 11b is bored in the fitting part 11a.

Further, the lock knob 12 is made of polypropylene,
It is made of synthetic resin such as vinyl chloride resin. The upper end 12a of the lock knob 12 has a concave central portion so that it can be easily handled by hand.
In the lower part 12b of the lock knob 12, a slot part 13 is formed in the vertical direction and has a substantially U-shaped cross section, and is open at the lower end for fitting the fitting part 11a of the lock lever 11 thereinto. Further, in the lower part 12b, a plurality of lever mounting holes 14 are formed perpendicularly to the slot portion 13 at appropriate intervals in the vertical direction.

Therefore, lock knob 12 and lock lever 1
1, the fitting part 11a is first fitted into the slot part 13 of the lock knob 12. Next, by sliding the lock lever 12 up and down,
As shown in FIG. 2A and FIG.
After adjusting the protrusion L2 of the lock lever 1,
Finely adjust the lock knob 12 by moving it up and down so that the lever attachment hole 14 of No. 2 and the bolt insertion hole 11b of the lock knob 11 are located on the same line. In this state, the bolt 7 is inserted into each hole 14, 11b from the direction of the arrow and tightened and fixed. As a result, the locking means 10 can be moved from the tip of the locking knob 12 without being restricted by the size of the seat bag or by the position of the locking means 10.
It can be easily adjusted to the dimensions T1 and T2 up to.

<<Effect of the invention>> As explained above, according to the lock knob structure of the invention, by selecting the lever mounting hole,
Since the length from the disposed position of the locking means to the tip of the locking knob can be adjusted, the same locking knob can be used even if the size of the seat bag or the position at which the locking means is disposed changes.
