Description

  The present invention relates to a vehicle seat having a trunk-through structure in which an armrest and a lid that can be moved forward are stored in a recessed state provided in a seat back, and a lid is stored in an upright state.

A retractable armrest is provided in a standing position by providing a recess in a part of the seat back, and a passenger space (passenger room) and a luggage space (luggage room) for storing luggage, etc., with a part of the recess as an opening. The trunk-through structure that enables communication is used for vehicle seats such as rear seats (second seats and third seats).
When the armrest is stood and stored in the recess of the seatback, the opening of the seatback recess is covered with the armrest, the passenger compartment and the luggage compartment are not communicated, the armrest is tilted forward, and the opening of the seatback recess is released. As a result, the passenger compartment and the luggage compartment communicate with each other, and a long object such as a ski is accommodated in the luggage compartment and the passenger compartment via the opening.

There is also known a configuration in which the lid is stowed in the recessed portion of the seat back behind the armrest in a standing state, and the lid is moved forward on the armrest moved forward to form a table. In this configuration, when both the armrest and the lid are tilted forward, the opening of the seat back recess is released, and the passenger compartment and the luggage compartment are communicated.
For example, Japanese Patent Laid-Open No. 2001-017266 describes a configuration in which a lid and an armrest are rotatably supported by a hinge pin (rotating shaft) provided at an end portion of a substantially U-shaped bracket. In the configuration in which the lid and the armrest are attached to the bracket with a common hinge pin, the lid cannot be easily assembled in the seat back recess.

  There is also known a configuration in which a part of a concave portion of a seat back serving as an opening is surrounded by a substantially rectangular frame and a lid is attached to the frame so as to be rotatable. Here, the lid and the frame are usually formed of plastic, and hinge pins (rotating shafts) extending from the lower end of the lid to the left and right are the corresponding cylindrical hinge pieces (support pieces) formed on the frame. ), The lid is pivotally attached to the frame body.

JP 2001-017266 A

  In a configuration in which the hinge pin (rotating shaft) at the lower end of the lid is fitted to the corresponding cylindrical hinge piece (support piece) of the frame body and the lid is rotatably attached to the frame body, the lid of the lid is attached to the cylindrical hinge piece. An open notch, that is, a cut groove serving as a guide for inserting and fitting the hinge pin is formed in the upper part of the hinge piece. Then, the hinge pin of the lid is pushed from above into the groove at the upper part of the hinge piece, so that the hinge pin can be inserted and fitted into the hinge piece, and the lid can be easily assembled into the frame.

  For example, when the armrest is tilted forward while the lid is stored in the recess, if the luggage in the luggage compartment hits the seat back from behind, the lid falls on the armrest due to the impact. Then, the lid rebounds on the armrest, the hinge pin at the lower end (back end) of the lid is lifted, the hinge pin falls out (jumps out) from the upper groove of the hinge piece, and the hinge pin and the hinge piece are disengaged. There is a fear.

  The present invention provides a vehicle seat having a trunk through structure that prevents the hinge pin of the lid from coming off from the hinge piece of the frame body even when the lid rebounds on the armrest, and can maintain the fitting state of the hinge pin and the hinge piece. The purpose is to provide.

For the above purpose, in the present invention, the position of the kerf provided in the hinge piece is changed from the upper part to the front part.
That is, according to the first aspect of the present invention, a recessed portion capable of communicating with the passenger compartment and the luggage compartment is provided in the seat back with a part thereof as an opening, and the armrest that can be moved forward is stored in the recessed portion in a standing state, A part of the recess of the seat back is surrounded by a substantially rectangular frame, and the hinge pin extending outward is formed on the left and right at the lower end of the lid, and the hinge pin extending left and right from the lower end of the left and right lids extending outward Is fitted to the corresponding cylindrical hinge piece provided on the frame body, and the lid is rotatably attached to the frame body, and is stowed in the seat back recess behind the armrest, and the hinge pin to the hinge piece is A kerf that guides insertion is formed in the front part of the hinge piece of the frame body, and the hinge pin of the lid has a small diameter part that can pass through the kerf of the hinge piece and a large diameter part that cannot be removed from the kerf. Oval cross section Formed into Jo, the large diameter portion is formed in a shape extending inclined forward of the seat relative to the lid thereof.

According to the second aspect of the present invention, the kerf is formed only on one hinge piece of the frame.

  In the present invention according to claim 1, since the kerf is not formed in the upper part of the hinge piece, even if the lid falls over the armrest and rebounds, the hinge pin at the lower end (back end) of the lid is lifted by the hinge piece. This prevents the hinge pin from falling off the hinge piece. Therefore, even if the lid rebounds, the fitting of the hinge pin and the hinge piece is not released, and the fitting state is maintained.

Furthermore, in the present invention according to claim 1 , the small-diameter portion can be easily inserted and fitted into the hinge piece by aligning the small-diameter portion with the kerf, and the large-diameter portion is fitted into the hinge piece to prevent rattling. The lid is blocked and can be mounted without backlash. In addition, the small-diameter portion of the hinge pin is positioned greatly deviated from the cut groove of the hinge piece, and the hinge pin can be reliably prevented from falling off from the hinge piece during rebound.
In the present invention according to claim 2 , since the kerf is formed only in one hinge piece of the frame body and no kerf is formed in the front part of the other hinge piece, the lid is formed by the hinge piece without the kerf. Can be reliably prevented from falling off.

A kerf that guides the insertion of the hinge pin into the hinge piece is formed in the front part of one of the hinge pieces, and the hinge pin has a small diameter part that can pass through the kerf of the hinge piece and a large diameter that cannot be removed from the kerf. It is formed into an oval cross-sectional shape having a portion. The long diameter portion of the hinge pin is formed to be inclined forward with respect to the lid itself, and the hinge pin is inserted into the hinge piece of the frame body from the front by aligning the small diameter portion with the cut groove and guided by the cut groove. Combined.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 and 3 are a front perspective view and a partially broken rear perspective view of a vehicle seat having a trunk-through structure according to an embodiment of the present invention. FIG. 2 shows a schematic side view of the central sheet of FIG. In the figure, the front, rear, left and right sides of the seat are indicated by Fr, Rr, L, R on the basis of the seated person.

As shown in FIG. 1, the vehicle seat 10 is a rear seat (second seat, third seat) that is divided into a lateral width of 6: 4 to become a two-person seat 10a + 1 a person seat 10b, A recess 12 is formed in the seat back 10c ′ of the central seat 10c set near the center of the two-person seat.
As can be seen from FIG. 2 in addition to FIG. 1, an armrest 14 and a lid 16 that can be moved forward are stored in the recessed portion 12 in an upright state with the armrest facing forward, and if the armrest 14 is moved forward, The armrest can be used effectively instead of making it difficult to sit on the central seat 10c. Further, if the lid 16 is moved forward on the armrest 14 that has been moved forward, the lid can be used as a table.

As shown in FIG. 2, the lower end of the armrest 14 is rotatably attached to a bracket (not shown), and a part of the recess 12 is opened. Further, as shown in FIG. 3, a substantially rectangular frame 20 surrounding the opening 18 is fixed to the back surface of the seat back 10c ', and the lower end of the lid 16 is rotatably attached to the frame. Yes. Then, the lid 16 is stored in the seat back recess 12 in an upright state, whereby the opening 18 of the recess is closed with the lid.
As can be seen from FIG. 2, when the lid 16 is moved forward together with the armrest 14, the opening 18 in the seat back recess is released, the passenger compartment DS and the luggage compartment LS are communicated, and long objects such as skis open the opening 18. It can be accommodated in a luggage compartment and a passenger compartment.

4 is a schematic plan view of the frame, and FIG. 5 is a schematic plan view of the lid.
For example, the frame 20 and the lid 16 are both made of plastic. As shown in FIG. 4, the frame 20 has a recessed portion 20b surrounded by a protruding edge 20a on its surface (a surface located on the front side of the vehicle body). ) Having a substantially rectangular shape on the inside, and a part of the protrusion edge is formed in a hook shape at the upper center of the protrusion edge 20a. Then, the lid 16 in the standing state is supported by the flat support surface 20c behind the recessed portion 20b, and the upper edge of the lid is locked to the hook piece 20a ′ at the upper center of the projecting edge 20a. It is supported by the frame 20 in a state (refer to AA sectional view and BB sectional view).

  In addition, cylindrical hinge pieces (support pieces) 20 d extending inward are formed on the left and right sides of the lower end of the frame body 20. Of the left and right hinge pieces 20d, one of the hinge pieces, for example, the hinge piece 20dL, has a cut groove (released notch) 20d ′ formed in a front facing portion (front portion). (See enlarged view of arrow C).

  On the other hand, the lid 16 has a substantially rectangular shape similar to the frame so that it can be supported by the support surface 20c of the frame, and as shown in FIG. 5, a hinge pin (rotating shaft) 16a extending outward is provided. Molded on the left and right of the lower end of the lid. The left and right hinge pins 16a have a substantially oval (so-called oval shape) cross-sectional shape, the small diameter portion of which is a size (width) that can pass through the groove 20d 'of the hinge piece of the frame, and the large diameter portion of the hinge piece 16a It is formed in a size (major axis) that can be fitted to 20d leaving a slight gap. Here, the substantially oval hinge pin 16a has a large-diameter portion (long-diameter portion) that is inclined forward (falling forward) with respect to the lid 16 itself (the lid main body) and extends. The inclination angle (forward inclination angle) θ is, for example, 15 ° to 45 ° with respect to the lid body, and is 20 ° in the embodiment (see the enlarged view of the arrow C).

6A and 6B show an enlarged view of arrow C ′ and an enlarged view of arrow C in FIG.
The fitting of the hinge pin to the hinge piece will be described. First, the hinge pin 16a of the lid is formed on the hinge piece substantially parallel to the hinge piece from the distal end side of the hinge piece with respect to the hinge piece 20d (20dR) having no kerf. Inserted (see arrow C ′ enlarged view). Then, the hinge pin 16a of the lid is guided by the cut groove and inserted into the hinge piece with respect to the hinge piece 20d (20dL) in which the cut groove 20d ′ is formed (see the enlarged view of arrow C). Since the large-diameter portion of the hinge pin 16a is inclined 20 ° forward with respect to the lid main body 16, the lid 16 can be made to the horizontal line H by inserting the large-diameter portion horizontally into the hinge piece. The frame body is fitted in a state where it is lifted by 20 °. Since the fitting can be performed with the rod 16 being lifted, the hinge piece 20d and the hinge pin 16a can be easily fitted.

FIGS. 7A and 7B are views corresponding to the enlarged view of the arrow C in FIG. 6B when the lid is stored in the seat back recess and when the lid is tilted forward. In addition, in FIG. 7, it is displayed on the opposite side of the arrow C enlarged view of FIG.
As can be seen from FIG. 2, since the seat back 10c ′ is tilted rearward, when stored in the seat back recess 12, the lid is seated together with the frame 20 as shown in FIG. It stands upright by the same angle as the back tilt angle.

For example, if the rearward tilt angle of the seat back is 20 °, the lid 16 and the frame body 20 are also tilted backward by 20 °. 7A, the center line C of the cut groove 20d ′ of the hinge piece of the frame body is opened with an inclination of 20 ° upward with respect to the horizontal line H. As shown in FIG. On the other hand, the large-diameter portion of the hinge pin 16a that extends by tilting 20 ° forward with respect to the lid body is located on the vertical line, and is tilted 70 ° with respect to the kerf (precisely the horizontal line of the kerf). Located.
In addition, as can be seen from FIG. 7B, in a state where the lid is used as a table that is tilted over the armrest 14 and positioned horizontally, the lid is 110 ° (20 ° + 90 °) from the standing state of FIG. ) Since it is rotated, the large-diameter portion of the hinge pin 16a of the lid is positioned at an angle of 40 ° with respect to the cut groove 20d ′ of the hinge piece.

  When only the armrest 14 is tilted forward and the lid is stored in the seatback recess 12, when the luggage La in the luggage compartment LS hits the lid 16 from behind, the lid falls on the armrest by the impact (see FIG. 2). When the lid 16 rebounds on the armrest 14, the hinge pin 16a at the lower end (back end) of the lid is lifted and tends to escape upward.

  However, the groove 20d 'of the hinge piece is formed in the front part of the hinge piece, and is not formed in the upper part of the hinge piece 20d corresponding to the direction (upward direction) in which the hinge pin 16a tends to escape. Therefore, the lifting of the hinge pin 16a is prevented by the hinge piece 20d, the hinge pin is prevented from coming off from the hinge piece, and the fitting state of the hinge pin and the hinge piece is not released and the fitting state is maintained.

  If the hinge pin 16a of the lid has a substantially oval cross section and its long diameter portion is formed to be inclined and extended forward with respect to the lid main body, 7 (B), when the lid is in a horizontal position, the large-diameter portion of the hinge pin 16a of the lid is inclined by 40 ° with respect to the groove 20d ′ of the hinge piece, and the small-diameter portion of the hinge pin is cut. It deviates greatly from the groove and does not align with the groove. Therefore, the hinge pin 16d ′ is prevented from falling off (jumping out) through the kerf 20d ′, there is no possibility that the hinge pin is detached from the hinge piece, and even if the lid 14 rebounds on the armrest 16, the hinge pin and hinge piece Mating is reliably maintained.

  Further, since the kerf 20d ′ is not provided on both the left and right hinge pieces 20d, but only on one of them, the hinge piece not provided with the kerf ensures that the hinge pin is removed from the hinge piece. Can be prevented.

  As described above, according to the present invention, since the kerf is not formed in the upper part of the hinge piece, even if the lid falls on the armrest and rebounds, the hinge pin lifts at the lower end (back end) of the lid. It is blocked by the piece, and the fitting of the hinge pin and the hinge piece is not released and the fitting state is maintained.

  The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention. All modifications, alterations, etc. within the technical scope of the present invention are included in the present invention. Needless to say.

For example, in the embodiment, the kerf at the front portion of the hinge piece of the frame is formed so that the center line thereof coincides with the horizontal line. The line may be formed at an angle of 10 ° to 20 ° upward with respect to the horizontal line.
The hinge pin of the lid has a long-diameter portion that is inclined forward by 15 ° to 45 °, for example, 20 ° in the embodiment with respect to the lid body, but this forward inclination angle is appropriately selected from the relationship with the kerf. It is possible and is not limited to the exemplified values.

  The present invention can be widely used for vehicle seats used as rear seats (second seats, third seats) and the like.
