Description

Detailed Description of the Invention a. Field of Industrial Application This Q4 relates to reclining devices for automobiles. Akira Miki! tar 4t4
However, according to the device disclosed in the publication, the sill rubber is arranged to sandwich the seat back arm, and this arm moves back and forth. There is a risk of it bending inward, and if you bend it inward, the force pushing the arm will become stronger.
Motion kanabu (naru).

Also, if the ambient temperature becomes high, the seal rubber becomes soft and waving occurs, and if the ambient temperature becomes low, the seal rubber becomes hard and the force that pinches the seat back arm becomes stronger.

Also, if the ambient temperature is low and the rubber is left in the reclined position for a long time, the rubber will adapt to the shape of the seatback arm, and when the seatback arm is moved to another position, the shape will remain as it is, which may affect the appearance. There is a risk that a defect may occur, or a gap may be created between the fin pieces that are still upright, causing problems such as thin plate-shaped small items such as coins falling into place.

Furthermore, one side of the seal rubber is fitted in advance to the seat cushion arm, and the other side of the seal rubber is fitted in advance to the inside of the reclining lock cover, and only when the reclining lock cover is attached to the seat cushion arm. Since the fins on both sides of the seal rubber face each other, if a positioning error occurs due to an installation error or a one-part precision error, the cost of reassembling or replacing parts is expected to increase, which is one of the causes of rising costs. ing.

The present invention has been made in view of these conventional problems, and aims to smooth the back and forth movement of a reclining device while maintaining its sealing function, and significantly reduce the number of assembly steps.

d9 Means for Solving Problems In order to achieve this purpose, the seat cushion 07 has a base to which the beam is fixed, an arm rotatably supported by the base, and an ear plug fixed to the arm. A lock plate having upper teeth on the lower side, a lock par which is also rotatably supported on the base and has lower teeth on the upper side and can be engaged with and disengaged from the upper teeth of the lock plate, and a lock plate that covers the members such as the arm. a cover supported by a base, and first and second seals each having a substantially circular shape extending to the vicinity of both teeth are disposed between the base and the lock plate and between the arm and the cover. , the second seal is provided with a protruding flange that can prevent the insertion of a thin plate such as a coin together with the protruding piece of the cover.Embodiment FIGS. 7 to 10 show an embodiment of the present invention. FIG.

First, the configuration will be described. / is a seat cushion, λ is a seat back, and 3 is a reclining device that connects a seat cushion l and a seat bar. The reclining device 3 has a base fixed to a frame (not shown) of the seat cushion, and a first shaft hole connected to a first pin a inserted into a seventh through hole 4ta of the paster.
The arm is rotatably supported at a and is prevented from being pulled out! and,
Similarly, the lock par≦ is rotatably supported by the second shaft hole 6a and is prevented from being pulled out with respect to the first pin a inserted into the second through hole g1) of the paster, and the third through hole of the base Hiro as well. The operation lever 2 is rotatably supported in the third shaft hole 7a with respect to the third pin C inserted in the third pin C inserted in the pin C, and is prevented from being removed, and the first to third pins a, ? b*? A locking hole tILatb11rC is formed to be inserted and locked into each of the first and second locking holes tILatb11rC, which are disposed so as to sandwich and cover the lock bar jJPs operation lever 7 with respect to the base. Tip 3 Pinta a
・It consists of a cover r supported by the base hiro with ri b119C.

Said arm! The first shaft hole! There is a locking hole around a! A plurality of b are formed. 10 is upper tooth 1 on the bottom side
00 formed lock plate, the lock plate)
/(Insert the bottle IC into the locking hole 10b of 7 and the locking hole jb, and the protruding piece ra of the cover r that is caulked will prevent a coin from entering between the operating lever 2 and the locking hole 6. The lock par 6 has lower teeth 6b formed on its upper side that can be engaged with and disengaged from the upper teeth 1OC of the lock plate io. Bolts 7b and 7c, which can be supported on the upper surface of the part 6C and on the lower surface 4ef, respectively, protrude from the base, and a cinch knob 7d is provided at the tip.Ol/ is the first seal, and the base and arm !, and 12 is a second seal, which is disposed between the armature and the cover, and both teeth 10c, &b, respectively.
It extends to the vicinity and is approximately circular in shape. To explain in more detail, first, the lock plate 10 is fixed to the arm by crushing both ends of the bottle jc, and a notch having the lip portion//a of the first seal/I is formed in the flange of the bottle jc. Insert ftt3, the hole /Q that has the lip portion ti bik, and the hole tS that does not have the lip portion //a, //b. Then, the lip portion //a reliably clamps and supports the pin IC due to the inner diameter of the lip portion //a, which is formed to be smaller than the diameter of the flange portion of the bottle jc. In this way, the gap tt with the paster lock plate IO
After integrating the arm j, the lock plate 10, and the first seal l/ so that the seal// is filled in, it is assembled into the paster via the first pin 9a, and the arm! A second seal 12 is placed on the side so that the pin IC escapes, and the flange/
2. Insert a, then arrange the cover l and place the 7th to 3rd bins? Assembling is completed by caulking the end of the ba9c. The symbol /6 of the first seal l/ is a through hole such as the seventh pin 9a, and the symbol llc is a thinned portion of the first seal l/, and the lip //a.

//b is fixed at both ends to form a half-moon-shaped through hole 17 to avoid stress, but it may also be opened on the outside to form a peninsular lip. 1st seal/l
The flange 2a is the arm! Second sticker! It is formed to fill the gap between 2.

Next, the effect will be explained. If you want to tilt the seat back 2ft forward or backward, move the operating lever 7 in the direction of arrow B1 in Figure 4.
When the pin 7C is rotated in the direction shown in FIG.
rotates in the direction of the arrow C2 under its own weight, the lower tooth O comes off from the upper tooth 100 of the lock plate IO, and the arm j becomes freely rotatable in the front-rear direction (At r At direction). When it is turned in the direction of arrow B2, the pin 7C of the lever 7 rotates the lockper in the 01 direction, the lower teeth ≦b of the locker 6 and the upper teeth 10Q of the lock plate 10 engage, and the arm j becomes At* 4 Rotation in any direction is stopped and the seat bar is fixed. And at any of these times, the 1st and 2nd seals //
, /2 prevents thin objects such as coins from entering from the direction indicated by the arrow in FIG. arm! Even if the cover falls backward, the gap between the lock play) 10 and the protruding piece ♂d of the cover r will not widen at all, and small items such as coins will not get in there. In addition, the lip portions //a and //b of the first and second seals // and /2 and the holes 14C prevent stress from being applied, so there is not much change in heat. It turns out that.

f. Effect As explained above, according to the present invention, it is possible to enhance the sealing effect with respect to the base without causing rotation of the arm or rotation failure, and furthermore, it is easy to assemble. In addition, there is no need for adjustment, resulting in a significant cost reduction.Furthermore, by providing a ring on the first seal, there is a part to escape heat and force, so undue stress will not occur. It has practical effects such as:
