Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular seat provided in a passenger compartment, and more particularly to a vehicular seat with a storage compartment having a storage compartment below a seat cushion.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No.
As described in JP-A-324185, right and left rails may be provided in the front-rear direction of the lower surface of a cushion frame which is a core material of a seat cushion, and the case may be installed on the rails so that the case can be pulled out. FIG. 5 schematically shows such a conventional case structure. The cushion frame 50 is a pressed product of a metal plate material for holding the cushioning pad, and the main portion 50a is formed one step lower than both side portions 50b. Two rails 51 that are located on the left and right and extend in the front-rear direction are fixed to the main part 50a. Each rail 51 has a U-shape, an upper portion 51a is attached to the main portion 50a by welding, and a lower portion 51b is set as a holding portion. The case 53 is a resin molded product, and is held slidably back and forth with the flange portions 53a on both sides inserted into the U-shape of the both rails 51. The case 53 is usually stored in the lower part of the cushion frame 50, and unlocked by a locking means (not shown) when necessary, and is pulled out along both rails 51. Therefore, the occupant can store and remove small items in the case 53 even in a seated state.

[0003]

In the conventional storage structure, the number of parts and the weight are increased because the rails 51 are attached to the cushion frame 50, and the two rails 51 are required.
It is difficult to reduce the number of assembling man-hours because it performs dimensioning and welding work between them. In addition, the conventional structure is disclosed in Japanese Patent Application Laid-Open No. H10-324185.
As described in the above item, the sliding restricting means and the locking means of the case 53 are complicated, and it is difficult to reduce the manufacturing cost including this point.

[0004] An object of the present invention is to solve the above-mentioned problems. Specifically, it is an object of the present invention to improve the number of parts, the weight, and the number of assembling steps in a vehicle seat with a container using a bread-type cushion frame, thereby realizing cost reduction.

[0005]

In order to achieve the above object, the present invention provides a cushion frame 5 as illustrated in the drawings.
Is made of a pressed metal plate, and has a left and right rail 15 provided on the lower surface and extending in the front-rear direction, and a case 10 which is held by the left and right rails 15 so as to be able to be pulled out. In the vehicle seat 1, the left and right rails 15 are each substantially L-shaped using a part of the bottom plate portion of the cushion frame 5, and the L-shaped horizontal plate portion 1 is used.
The case 10 is formed by cutting and raising the case 5b so as to face the case 10, and the case 10 is held by slidably mounting the flange-like flange portions 11c provided on the left and right sides of the case 10.

According to the invention described above, the cushion frame 5 is formed by pressing a metal plate material, and the both side portions 5 are formed.
In some cases, the design may be such that the main part 5a between the points b is lowered by one step, and the design is devised by focusing on such a core material form. That is, in this structure, the rail corresponding portion can be simultaneously contoured or further bent downward from the main portion 5a at the time of pressing the cushion frame 5, so that positioning and welding work between rails can be eliminated as in the related art, At the same time, since both rails 15 are formed using a part of the cushion frame 5, there is an advantage that the total seat weight can be reduced by the rail weight of the conventional product.

The above invention is more preferably embodied as follows. First, the left and right rails 15
That is, the plurality of cushions 15A, 15B, and 15C provided on the bottom plate portion of the cushion frame 5 are provided as a set. This is because there is no danger that the strength of the cushion frame 5 itself is reduced by arranging the rails 15 back and forth as in the embodiment, and the holding of the pad 6 held on the main portion 5a as the bottom plate portion. Maintaining characteristics is significant. Second, the bottom plate of the cushion frame 5 has the stopper pieces 16 and / or 17 cut and raised corresponding to the L-shaped horizontal plate portions 15b of the left and right rails 15, while the case 10
Is a configuration in which a contact piece 13 is provided on the rear side to abut on the stopper piece and to be restricted in sliding. This is because, for example, when the case 10 is pushed in along the rail 15 from the drawn-out position by the stop piece 16 and / or 17 on the cushion frame side and the contact piece 13 on the case side,
The sliding can be restricted at the regular storage position. Structurally, since the stopper pieces 16 and / or 17 are also formed as a part of the seat cushion frame 5, the above-described weight reduction and the like can be further achieved, and the contact piece 13 can have a simple shape. And can be formed integrally with each other.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a vehicular seat with a storage compartment to which the present invention is applied, FIG. 1 is a schematic configuration diagram of a longitudinal section of a seat cushion, FIG. 2 is an external view of a case, and FIG. FIG. 4 (a) to FIG.
(C) is a schematic side view for explaining the operation. In the following description, after an outline of the vehicle seat structure of the embodiment, the detailed configuration and operation of the main part of the case and the cushion frame will be described in detail.

(Overall Overview) A vehicle seat 1 with a storage box according to an embodiment comprises a seat holding portion including a seat cushion 2 and a seat back 3 as shown in FIG. The case 10 is provided so that an occupant can use the case 10 as needed. Here, the lower portion of the seat cushion 2 is mounted on left and right slide members 4 and 4 constituting a slide mechanism, and the whole is supported via both rail members 4 and 4 so as to be movable and adjustable in the front-rear direction. . The basis of the seat cushion 2 and the seat back 3 is the seat cushion 2 shown in FIG.
As in the example on the side, a cushioning pad 6 is held on a cushion frame 5 (a back frame in the seat back 3), and the cushioning pad 6 is covered with a bag-shaped skin 7. Also, usually
The seat back 3 is attached to the seat cushion 2 so as to be adjustable in angle. In the above-described slide mechanism, the slide member 4 includes a fixed lower rail 4a and a movable upper rail 4b. The lower rail 4 a is fixed to the vehicle body floor F via the bracket 8.
May be omitted and fixed directly. The upper rail 4b is moved back and forth by a predetermined range along the lower rail 4a, and is prevented from moving with the lower rail 4a at an arbitrary position by a lock means (not shown). The slide mechanism has a side bracket 9 provided below the lower surface of the side portion 5b of the cushion frame 5 and connected to the upper rail 4b, and holds the seat cushion 2 via the side bracket 9. Such a slide mechanism itself is the same as or similar to the conventional one.

(Case Structure) The case 10 of the embodiment is a rectangular three-dimensional container made of a resin molded product as shown in FIG.
It has a flange-shaped flange portion 11 provided on the upper periphery.
The flange portion 11 includes a front flange portion 11a having a small rectangular through hole 11d formed at an intermediate portion thereof, a rear flange portion 11b having an abutting piece 13 standing upright from near both sides, and
It is composed of both side flange portions 11c which are portions held on the cushion frame 5 side. Flange part 11c
The lower edge portion is formed in a semi-cylindrical cross section as shown in FIG. 1 and is easily slid while being held on the rail 15 as described later. On the front side of the case 10, a pair of support portions 12 are integrally provided at a front intermediate portion as shown in FIG. A latch member 14 is swingably supported between the support portions 12 via a pin 14a, and is urged in a counterclockwise direction by an unillustrated urging spring. This latch member 14
Has an operating lever portion 14b projecting forward and an engaging claw portion 14c projecting upward from the through hole 11d. Normally, the engaging claw portion 14c is in a locked position where it protrudes greatly from the through hole 11d under the urging pressure of the urging spring, and the operating lever portion 14b is moved upward against the urging force of the urging spring. When the button is pushed, the pin 14a is rotated about the fulcrum, and is switched to the unlocked position where the amount of protrusion of the engaging claw portion 14c from the through hole 11d is reduced. That is,
The latch member 14 serves both as a lock for the knob operating portion of the case 10 and a rail 15 which will be described later, and as a play prevention.

(Cushion Frame Structure) The cushion frame 5 according to the embodiment is made of a pressed metal plate material, and its peripheral portion is one step higher as can be seen from FIGS. Structurally, the main portion 5a is flat and lower than the peripheral portion including both side portions 5b, the main portion 5a and both side portions 5b are connected by an inclined portion 5c, Rails 15 (15A, 15B, 15C) are provided below the left and right sides of the lower surface side of 5a in the front-rear direction, and stopper pieces 16, 17 are provided correspondingly to the rails 15A and 15C. It is characterized by. When the cushion frame 5 is viewed from the upper side, openings 18a, 18b, 18c corresponding to the rails 15A, 15B, 15C are scattered from the front to the left and right of the main portion 5a.

That is, the left and right rails 15 are configured as a set of rails 15A, 15B, and 15C arranged side by side in the front-rear direction. Each of the rails 15A, 15B, and 15C cuts and raises a corresponding portion of the main portion 5a when the cushion frame 5 is press-formed, and furthermore, bends the middle horizontally so as to be substantially L-shaped.
It was formed into a shape. For this reason, the L-shaped vertical portion 1
5a is connected to the main portion 5a, and is an L-shaped horizontal portion 15b.
Is substantially parallel to the main portion 5a. The left and right rails 15A, 15B, and 15C are arranged such that the horizontal portions 15b face each other, and the horizontal portions 15b are located at the same height from the main portion 5a, that is, on the same plane. The space between the left and right rails 15 corresponds to the size between the two side flange portions 11c of the case 10, and can receive the corresponding side flange portions 11c on the opposed left and right horizontal portions 15b. That is, the case 10 is slid in the front-rear direction along the left and right rails 15 in the receiving and holding state. on the other hand,
The distance between the rail 15A and the rail 15B, and the rail 15
The distance between B and the rail 15C is set so that when the case 10 is pulled forward as shown in FIG. Therefore, the left and right rails 15 can be composed of two rails, but in this case, the interval is set so that the case 10 is not carelessly inclined or dropped while being pulled out or pushed in. As long as the above conditions are satisfied, the left and right rails 15 may be shifted back and forth, for example, without arranging the left and right rails 15B.

The stopper pieces 16, 17 are simple vertical pieces. Of these, the stopper piece 16 is the rail 1
5A, it is cut and raised so as to intersect with the vertical portion 15a, and when the case 10 is pulled out to the maximum, the contact piece 13 hits and restricts the case 10 from falling off. The stopper piece 17 is cut and raised in a position intersecting with the vertical portion 15a corresponding to the rail 15C, that is, in a state facing the stopper piece 16, and when the case 10 is pushed in, the contact piece 13 comes into contact with the Restrict 10 from being pushed more than necessary.
Therefore, each of the stopper pieces 16 and 17 may correspond to the position where the contact piece 13 of the case 10 is provided. For example, when the contact piece 13 is set at the left and right middle of the rear flange 11b, The portion of the cushion frame 5 different from the rails 15A and 15C is cut and raised.
Further, in this embodiment, a striker 19 corresponding to the above-described latch member 14 is provided on the front side of the main portion 15a. The striker 19 has a substantially U-shaped cross section, and is a simple one that abuts and engages the engagement claw portion 14c of the latch member 14 with the U-shaped inner surface.

(Assembling and Operation) When assembling the case 10 to the rail 15 described above, for example, the case 10 is inclined, and the stopper piece 16 is made to escape from the rear side of the case with respect to the horizontal portions 15b of the left and right rails 15. It is held as shown in FIG. The case 10 is pushed into the rear of the seat cushion from that state. However, the case 10 is pressed slightly more because the engagement claw portion 14c of the latch member 14 is slightly in front of the striker 19 in FIG. Alternatively, when the operating lever 14b is lifted and pressed against the urging force of the urging spring as shown in FIG. 8B, the engaging claw 14c rides over the front surface of the striker 19 and is located at the storage position. At this time, the case 10 is
Strikes the stopper piece 17 and is arranged at the regular storage position. In this storage position, the case 10 is biased toward the striker 19 via the spring member and the latch member 14 described above. When the object is taken in and out of the case 10, the operation lever 14b picked by hand is pushed upward as shown in FIG. 4B, and the case 10 is moved forward with the engagement of the engagement claw portion 14c with the striker 18 released. Withdraw to The maximum withdrawal position of the case 10 is regulated by the contact piece 13 abutting on the stopper piece 16 as shown in FIG. Returning to the original storage position is as described above.

The present invention is not limited to the above-described embodiment as long as it satisfies the requirements specified in the claims. As an example, the rail 15 is connected to the rail 15A, 1
5B and 15C, the rails 15A and 15C are provided as long as the strength and rigidity of the cushion frame 5 can be satisfied.
B and 15C may be formed continuously, or may be constituted by the front and rear rails 15A and 15C as long as the case 10 does not fall down during drawing or the like. Also, the cushion frame 5
It is sufficient that the metal plate is a pressed product of a metal plate and has a substantially flat bottom plate portion, that is, a main portion 5a, and the detailed shape can be variously changed according to a pad holding shape or the like.
