It is connected to 51R integrally,
A seat slide device characterized by that.

[4] Configuration 4
In any of Configuration 1 to Configuration 3,
Claw receiving portions 11h and 51h are formed in the bent portion 11b of the covered side portion 11 of the lower rail 1 and the bent portion 51b of the reinforcing covered side portion 51 of the rear end bracket 5, respectively, and the bent portion of the upper rail hem side portion 21 is formed. A claw 21e that can be engaged with the claw receiving portions 11h and 51h is formed to protrude from the front end side edge 21d.
When the upper rail 2 is deformed by an impact tensile force transmitted from the belt anchor and its skirt 21 is locked to the lower rail cover 11 and / or the rear end bracket reinforcing cover 51, the claw 21e is engaged with the claw receiving portions 11h and 51h.
A seat slide device characterized by that.

The configuration 1 includes a long upper rail 2 to which a belt anchor is linked so as to be slidable on the long lower rail 1 and is fixed to a floor surface via a bracket attached to the lower rail 1. In the seat slide device, the upper rail 2 includes a skirt 21 that extends laterally from a lower edge of a vertical plate 20 (first vertical plate 201) extending in the rail longitudinal direction and is bent upward. The lower rail 1 has a covered side portion 11 that extends upward from the long edge of the bottom plate 10 extending in the rail longitudinal direction and is bent so as to cover the bent distal end side 21d of the upper rail hem side portion 21. The rear end bracket 5 attached to the rear end portion of the lower rail 1 has a floor extending from the rail attachment portion 50 attached to the rear end portion of the lower rail to the rear side via the intermediate portion 53. It is fixed to the floor surface by an attachment portion 55, and the rail attachment portion 50 is formed by extending a reinforcement covering side portion 51 having a bent portion 51b that can cover and wrap the bending tip side 21d of the upper rail hem side portion 21. The seat slide is characterized in that, when the upper rail 2 is deformed by an impact tensile force transmitted from the belt anchor, the skirt side portion 21 can be locked by the reinforcing cover side portion 51 of the rear end bracket 5. Since it is a device, when the upper rail 2 is located closer to the rear end (= rearmost position), a shocking tensile force is transmitted from the belt anchor, and the upper rail 2 tries to peel off from the lower rail 1. Even so, the bent leading end side 21d of the upper rail hem side portion 21 is locked by the reinforcing cover side portion 51 of the rear end bracket 5 to prevent peeling. Since the thickness of the rear end bracket 5 is thicker than that of the lower rail 1, the reinforcing cover side of the rear end bracket 5 as in the configuration 1 is compared with the case where the upper rail hem side part 21 is locked by the cover side part 11 of the lower rail 1. The direction locked by the part 51 can be locked more firmly. Further, since the rear end bracket 5 is directly fixed to the floor surface unlike the lower rail 1, compared with the case where the upper rail hem side portion 21 is locked by the cover side portion 11 of the lower rail 1, the configuration 1. Thus, the direction locked by the reinforcement covering side part 51 of the rear-end bracket 5 can be locked more firmly.
In addition, when a shocking tensile force is applied from the belt anchor during non-rearmost, the upper rail hem side portion 21 is locked by the covered side portion 11 of the lower rail 1, but the tensile force acting in that case Is sufficiently smaller than the tensile force acting at the time of rearmost, so that peeling does not easily occur.

  According to Configuration 2, in the configuration 1, the covered side portion 11 of the lower rail 1 has a notch portion 110 at the rear end portion, and the reinforcing covered side portion 51 of the rear end bracket 5 is connected to the lower rail covered side portion 110. Since the seat slide device extends from the rail mounting portion so as to fill the notch, the lower rail 1 can be reduced in weight and the effects of the configuration 1 can be achieved. Further, the total volume occupied by the lower rail 1 and the rear end bracket 5 can be reduced.

  The configuration 3 is the configuration 1 or the configuration 2, wherein the rear end bracket 5 has a flange portion 54 integrally extending from the floor surface mounting portion 55 to form a substantially upright plate, and the front end of the flange portion 54 Since the seat slide device is characterized in that the side 54F is integrally connected to the rear end side 51R of the reinforcing covering portion 51, the structure of the bracket 50 is strengthened, and the operation of the configurations 1 and 2 is performed. The effect can be achieved more powerfully.

  According to Configuration 4, in any one of Configurations 1 to 3, the claw receiving portion 11h is provided on the bent portion 11b of the covered side portion 11 of the lower rail 1 and the bent portion 51b of the reinforcing covered side portion 51 of the rear end bracket 5, respectively. , 51h, and a claw 21e that can be engaged with the claw receiving portions 11h, 51h is formed on the bent tip side edge 21d of the upper rail skirt side portion 21 so as to project, and an impact tensile force transmitted from the belt anchor is formed. When the upper rail 2 is deformed by this and the bottom side 21 is locked to the lower rail covered side 11 and / or the rear end bracket reinforcing covered side 51, the claw 21e is moved to the claw receiving part 11h, Since the seat slide device is configured to engage with 51h, the upper end bracket 51 is used to move the upper lever when an impact tensile force is applied from the belt anchor. Action and effect of preventing the peeling engages Le 2, by the engagement of the pawl 21e- claw receiving portion 11h · 51h, is further enhanced.

FIG.

Embodiments of the present invention will be described below with reference to the drawings.
The illustrated seat slide device includes a bottom plate 10 of the lower rail 1 extending in the groove of the lower rail 1, that is, the longitudinal direction of the rail, a long side plate 11a erected from one long edge, and the other long edge. In a groove surrounded by the elongate second side plate 16a, a skirt portion 21 and a second skirt portion 26 along both lower ends of the stand plate 20 extending in the rail longitudinal direction of the upper rail 2 are provided. It is a device that is housed so as to be covered and supported so as to be movable (slidable) in the rail direction. In order to enable sliding, a roller or a ball (not shown) is interposed in the gap between the upper rail 2 and the lower rail 1.

  The upper rail 2 has a standing plate 20 in which two first standing plates 201 and second standing plates 202 extending in the rail longitudinal direction are stacked, and supports the seat on the upper portion of the standing plate 20. Further, a belt anchor (not shown) is connected to the vicinity of the rear end portion of the standing plate 20 directly or indirectly through another member. That is, they are linked.

  A skirt 21 is provided at the lower end of the first standing plate 201 along the rail longitudinal direction. That is, the bottom plate 21a extends in the lateral direction from the lower edge of the first standing plate 201, and the side plate 21b extends from the long edge of the bottom plate 21a further obliquely upward. The bottom plate 21a and the side plate 21b constitute a skirt portion 21.

  On the other hand, the second bottom plate 26 is provided at the lower end of the second upright plate 202 along the rail longitudinal direction. That is, the bottom plate 26a is extended from the lower end edge of the second upright plate 202 in the lateral direction opposite to the bottom plate 21a, and the side plate 26b is extended from the long edge of the bottom plate 26a by further bending upward. . The vicinity of the upper end of the instant plate 26b is bent and configured to hold the aforementioned ball (not shown). The bottom plate 26a and the side plate 26b constitute the second skirt portion 26. Note that the lower end of the second upright plate 202 is located slightly higher than the lower end of the first upright plate 201. The bottom plate 26a is wider than the bottom plate 21a. The side plate 26b is sufficiently wider than the side plate 21b, and the tip is at a sufficiently high position.

  The first upright plate 201 and the second upright plate 202 of the upper rail 2 constituted by these parts can be manufactured by bending and forming one metal plate. In addition, instead of forming a single metal plate, the first standing plate 201 and the second standing plate 202 may be configured by, for example, bending a single plate material upward in FIG. .

  The lower rail 1 includes a bottom plate 10 extending in the rail longitudinal direction, a side plate 11a extending obliquely upward from one long edge (one long edge along the rail longitudinal direction) of the bottom plate 10, and a front end side of the side plate 11a. It has a top plate 11b that is bent so as to be folded back to the opposite side (the side closer to the upright plate 20 of the upper rail 2), and a hanging plate 11c that is formed by bending the tip side of the top plate 11b obliquely downward. The top plate 11b and the hanging plate 11c are wrapped so as to cover the bent distal end side 21d of the skirt portion 21 of the upper rail 2. That is, the side 11 is constituted by the side plate 11a, the top plate 11b, and the hanging plate 11c.

  In a predetermined range of the rear end portion of the lower rail 1 (rear end portion based on automobile standards), the top plate 11b and the hanging plate 11c are notched (see FIG. 4A). The reinforcement covering side part 51 of the rear end bracket 5 is used.

  On the other hand, a side plate 16a extends vertically upward from the other long edge of the bottom plate 10 of the lower rail 1 (the other long edge along the rail longitudinal direction). The upper end of the side plate 16a is bent horizontally obliquely and upwardly approaching the upright plate 20 of the upper rail 2, thereby forming the top plate 16b. The top plate 16b is vertically extended from the tip of the top plate 16b. It is drooping. The side plate 16a, the top plate 16b, and the hanging plate 16c are wrapped so as to cover the front end side of the side plate 26b of the second hem side portion 26 of the upper rail 2. That is, the second covered side portion 16 is configured by the side plate 16a, the top plate 16b, and the hanging plate 16c. The above-mentioned balls are held by the space surrounded by the side plate 16a, the top plate 16b, and the side plate 26b of the upper rail 2, and the space surrounded by the top plate 16b, the hanging plate 16c, and the side plate 26b of the upper rail 2, respectively. The

In a predetermined range of the rear end portion of the lower rail 1 (rear end portion based on automobile standards), a lower portion of the side plate 11a is cut out (see FIG. 4B), and a rear end bracket to be described later is formed in the cutout portion 110b. Five stoppers (cut-and-raised portions) 58 are arranged.
The lower rail 1 composed of these parts can be manufactured, for example, by bending a single metal plate.

  The upper rail 2 and the lower rail 1 are provided with a lock mechanism that fixes the relative position in the rail longitudinal direction of the upper rail 2 to the lower rail 1 at a desired position. The locking mechanism of the illustrated seat slide apparatus is configured such that the engaging portion 31 protruding from the central portion of the lock member 3 that is one bent linear spring is connected to the standing plate 20 (first standing plate 201, second standing plate). 202), the lower plate 1c is inserted into the notch (not shown) between the locking plates of the lower plate 16c of the lower rail 1 and the insertion hole (not shown) of the side plate 26b of the upper rail 2. This is a mechanism for fixing at the position of the notch between the lock teeth.

  Unlocking is performed by depressing the operated portion 32 provided near the center of the lock member 3 and releasing the engaging portion 31 downward from the notch (not shown) between the lock teeth of the hanging plate 16c. . Reference numeral 205 denotes a locking portion formed by cutting and raising from the first standing plate 201 to lock both ends of the lock member 3.

The lower rail 1 is fixed to the floor of an automobile via a front end bracket (not shown) attached to the front end side and a rear end bracket 5 attached to the rear end side.
Since the front end bracket is the same as the conventional one, description thereof is omitted.

  In the seat slide device, the rear end bracket 5 is attached to the lower surface of the rear end of the bottom plate 10 of the lower rail 1 (rear end based on automobile standards). This portion is referred to as a rail attachment portion 50 in this specification. Note that the rear end bracket may be attached to the side plates 11a and 16a instead of the lower surface of the rear end of the bottom plate 10, for example.

  As described above, the rear end bracket 5 includes a rail attachment portion 50, an intermediate portion (step portion in the present seat slide device) 53 that extends rearward from the rail attachment portion 50 (rearward on the basis of the automobile), A floor surface mounting portion 55 extending further rearward from the intermediate portion 53 is provided. In this floor surface mounting portion 55, the rear end bracket 5 is fixed to the floor surface of the automobile.

From one edge along the rail direction of the rail mounting portion 50 (the edge on the same side as the side plate 11a of the lower rail 1), the side plate 51a extends in the same manner as the lower rail 1, and similarly, the top plate 51b and the hanging plate 51c It is bent. The side plate 51 a is provided so as to wrap the outer surface side of the side plate 11 a of the lower rail 1. Further, the top plate 51b and the hanging plate 51c are formed in a cutout portion 110 (see FIG. 4A) formed by cutting out the top plate 11b and the hanging plate 11c in a predetermined range of the rear end portion of the lower rail 1. It is provided to be appropriated.
In FIG. 1, the top plate 51b and the hanging plate 51c are provided so as to overlap the top plate 11b and the hanging plate 11c of the lower rail 1 on the front side, but this shows an example of arrangement, It does not necessarily need to be provided so that it may overlap.

Thus, since the side plate 51a, the top plate 51b, and the hanging plate 51c are provided in the rail mounting portion 50 of the rear end bracket, when the upper rail 2 is located at the rear end (when it is in the rear most position). The side plate 21b of the upper rail 2 is covered and encased by the side plate 51a, the top plate 51b, and the hanging plate 51c of the rear end bracket 5. For this reason, the side plate 51a, the top plate 51b, and the hanging plate 51c of the rear end bracket 5 function in the same manner as the side plate 11a, the top plate 11b, and the hanging plate 11c of the lower rail 1. In view of this, in this specification, the side plate 51 a, the top plate 51 b, and the hanging plate 51 c are referred to as a reinforcing cover portion 51. Since this reinforcement covering side 51 is a part of the relatively thick rear end bracket 5, the covering side 11 (side plate 11 a, top plate 11 b, and hanging plate 11 c) is a part of the relatively thin lower rail 1. Thicker than). Accordingly, even if a shocking tensile force acts on the upper rail 2 from the belt anchor to cause the upper rail 2 to be peeled off from the lower rail 1, the side plate 21 b of the upper rail 2 is reinforced by the side cover 51 of the rear end bracket 5. Is firmly locked to prevent peeling.
Note that even when the impact force applied to the upper rail 2 is the same during non-rearmost, the deformation is smaller than during rearmost, so that there is a situation in which the engagement by the cover 11 of the lower rail 1 is sufficient during non-rearmost.

  Further, the above-described peeling prevention effect is a member in which the lower rail 1 is fixed to the floor surface indirectly via a bracket, whereas the rear end bracket 5 is directly fixed to the floor surface. It is further strengthened by the circumstances.

  On the other hand, a side plate 56a is extended from the other edge (the same side edge as the side plate 16a of the lower rail 1) along the rail direction of the rail mounting portion 50 in the same manner as the lower rail 1, and is cut near the lower end of the side plate 56a. A raising portion 58 is formed (see FIG. 1). In a predetermined range at the rear end of the lower rail where the cut-and-raised portion 58 is formed, the lower portion of the side plate 16a of the lower rail 1 is cut out (see FIG. 4B), and the cut-and-raised portion 58 is formed in the cut-out portion 110b. Is located.

  The cut-and-raised portion 58 is provided so that the tongue-like portion 28 formed by being cut and raised obliquely downward from the vicinity of the boundary between the bottom plate 26a and the side plate 26b of the upper rail 2 can be locked. In other words, the cut-and-raised portion 58 is provided so as to function as a stopper that regulates the rear end of movement of the upper rail 2. Thus, since a part of the rear end bracket 5 is used as a stopper for restricting the rear end of movement of the upper rail 2, there is no need to arrange another member, which contributes to the reduction in the number of parts and cost reduction.

  In the rear end bracket 5 of the seat slide device, a flange portion 54 erected from the edge of the floor surface mounting portion 55 is further integrated with the rear end side of the side plate 51b of the rail mounting portion 50 at the front end 54f. It is formed so that it may continue. For this reason, the strength of the rear end bracket 5 is further improved.

  In the above-described embodiment, the top plate 51b and the bottom plate 51c (reinforcing side portion) of the rear end bracket 5 are formed on the notch 110 formed by cutting out the top plate 11b and the bottom plate 11c in a predetermined range at the rear end of the lower rail 1. 51), the present invention is not limited to such a configuration. The present invention can be summarized as long as the bottom edge of the rear end of the upper rail 2 is accommodated in the rearmost in the space covered and covered with the reinforcing cover side (top plate / hanging plate) of the rear end bracket. For example, the same function can be realized by attaching the rear end bracket 5 without cutting out the top plate 11b and the hanging plate 11c at the rear end of the lower rail.

  Moreover, in the above-mentioned embodiment, the front end (bending front end side 21) of the side plate 21b of the skirt side part 21 of the upper rail 2 is connected to the reinforcing cover side part 51 of the rear end bracket 5 (the cover side part of the lower rail 1 at the time of non-rearmost). 11), the upper rail 2 is prevented from being peeled off. In order to further enhance this effect, the engagement teeth 21e are provided at the tip of the side plate 21b of the skirt portion 21 of the upper rail 2. The top plate 51b of the rear end bracket 5 and the top plate 11b of the lower rail 1 are provided with engagement holes 51e and 11e corresponding to the engagement teeth 21e, and the upper rail 2 is moved to the lower rail 1 by the action of impact tensile force. When they are about to be peeled off, they may be engaged to further improve the peeling prevention effect.
