  However, in the vehicle trunk through opening / closing device 100 having such a configuration, when the opening / closing part 102 is moved forward, the lock can be released only by pushing down the lever 101, and the opening / closing part 102 is actually moved forward. However, there is a problem that the operation of pulling the lever 101 further down in the forward direction is required while the lever 101 is pushed down, and therefore the trunk room E1 and the interior of the vehicle compartment E2 cannot be easily communicated.

  The present invention has been made in consideration of the above points, and it is an object of the present invention to provide a trunk through opening / closing device for a vehicle that can easily connect a trunk room and a vehicle interior.

  According to a first aspect of the present invention, a trunk through portion that is formed in a part of the seat back and communicates between the trunk room and the vehicle interior, and is provided rotatably on the lower side of the trunk through portion, and the seat cushion is moved forward. Armrest that can be pivoted on the lower side of the trunk through portion, and an opening / closing portion that can be forward-turned to the armrest in a forward-turned state, and a lock that locks the opening / closing portion in the trunk-through portion in an upright state Means, one end is attached to the armrest, and the other end is attached to the opening / closing part above the lower side of the trunk through part, the armrest in the forward-turned state, and the opening / closing part in the standing state Tensioning means for stretching between the two, and unlocking means for releasing the lock by the locking means.

  According to a second aspect of the present invention, a projection is formed at the lower end of the armrest, one end is attached to the stretching means, and the other end is provided below the projection of the armrest. An elastic means is provided that is fixed to a fixing means, and abuts against the protrusion when the armrest is tilted forward while the opening / closing part is in an upright state, and extends between the stretching means and the fixing means. I made it.

  According to a third aspect of the present invention, the elastic means is formed of a band-shaped rubber member, and when the armrest is tilted forward with the opening / closing portion standing, the planar surface of the rubber member is the protrusion. It was made to contact the part.

  According to a fourth aspect of the present invention, the stretching means is formed so as to cover from the front surface of the opening / closing portion to the upper surface of the armrest.

  According to the first aspect of the present invention, when the armrest is tilted forward while the opening / closing portion is in the standing state, the stretching means is stretched, and thereby the armrest is always placed on the opening / closing portion in the standing state. Since the front-end force can be applied to the side, the open / close section can be easily moved forward simply by releasing the lock of the open / close section by the unlocking means, and thus the trunk room and the passenger compartment can be easily moved. Can communicate.

  According to a second aspect of the present invention, when the armrest is tilted forward while the opening / closing portion is in the standing state, the stretching means is pulled downward by the elastic means, and the standing means is thereby stretched. The opening / closing part in the state can always be given forward force to the armrest side, and thus the opening / closing part in the standing state can be easily moved forward only by releasing the lock of the opening / closing part by the unlocking means.

  According to claim 3 of the present invention, even if the armrest is in an upright state and the rubber member is positioned between the armrest and the opening / closing portion, the rubber member does not get in the way. The armrest can be securely stored, and since the planar surface of the rubber member abuts on the protrusion, the rubber member can be easily deformed according to the shape of the protrusion, and thus the protrusion Damage to the part can be prevented.

  According to the fourth aspect of the present invention, the trunk through part can be covered with the stretching means so that the lower side of the trunk through part where the opening and closing part and the armrest are rotatably provided and the entire opening and closing part can be covered. The mechanical structure of the opening / closing part and armrest in the vehicle can be concealed, and thus the exterior of the vehicle trunk-through opening / closing device and the rear seat can be integrated, and the armrest can be used in a forward-turned state. It is possible to prevent the user from hooking a part of the clothes on a mechanical structure such as the opening / closing part when the user is in the room.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  In FIG. 1, reference numeral 1 denotes a vehicle rear seat as a whole. The rear seat 1 includes a seat cushion 2 and a seat back 3, each of which has a cushion pad attached to a frame (not shown) and a skin L attached thereto. Have

  The seat back 3 has a substantially central portion opened to form a trunk through portion 4, and the trunk through portion 4 is provided with a vehicle trunk through opening / closing device 5.

  The vehicle trunk-through opening / closing device 5 is provided with an armrest 6 rotatably on the lower side of the trunk-through portion 4 so that the standing armrest 6 can be accommodated in the trunk-through portion 4 and on the seat cushion 2 side. The armrest 6 can be moved forward.

  In addition to this configuration, the vehicular trunk through opening / closing device 5 has a skin cover 7 so as to cover from the upper side of the trunk through portion 4 to the upper surface 6A of the armrest 6.

  Here, as shown in FIG. 2, the vehicle trunk through opening / closing device 5 has a frame member 8 fitted around the trunk through portion 4, and a lower end portion of the opening 9 in the frame member 8 via a hinge portion 10. A thin-walled opening / closing part 11 is rotatably attached, and is configured to be able to move forward on the upper surface 6A of the armrest 6 in a forward-turned state.

  The vehicular trunk through opening / closing device 5 is locked when the lock plate 15 provided at the upper center portion of the frame member 8 comes into contact with the upper end portion 11A of the opening / closing portion 11, thereby causing the opening / closing portion 11 to stand upright. Thus, only the armrest 6 can be moved forward while maintaining the opening / closing part 11 in an upright state. At this time, the skin cover 7 extends from the front surface 11B of the opening / closing part 11 to the upper surface 6A of the armrest 6. It is made to cover.

  In practice, the skin cover 7 has one end selected to have the same length as the width dimension of the opening / closing portion 11, and is attached to the upper end portion 11 </ b> A of the opening / closing portion 11 by the skin fixing screw 16, and the other end is the armrest 6. The same length as the width dimension of the armrest 6 is selected and attached to the upper surface 6A of the armrest 6.

  Further, the length dimension in the longitudinal direction is selected so that the skin cover 7 is formed in a substantially curved shape from the upper end portion 11A of the opening / closing portion 11 to the upper surface 6A of the armrest 6.

  As shown in FIG. 3, a plate-like plate 17 is fixed to the back surface 7 </ b> A, and one end 20 </ b> A of a belt-like rubber member 20 is attached to both sides of the plate 17. Yes.

  Here, one end 20 </ b> A of the rubber member 20 is attached so as to be positioned in the vicinity of the upper portion of the protrusion 21 formed on the lower end portion 6 </ b> B of the armrest 6 when the armrest 6 is tilted forward to the seat cushion 2.

  On the other hand, the other end 20B of the rubber member 20 is fixed by a screw 23 to fixing means 22 disposed below and in front of the protrusion 21 of the armrest 6.

  Incidentally, in the case of this embodiment, one end of a belt-like armrest rubber member 24 is attached to the fixing means 22, and the other end of the armrest rubber member 24 is attached to the upper surface 6A of the armrest 6. When the armrest rubber member 24 is brought into contact with the protrusion 21 when the armrest 6 is moved forward, the armrest 6 is extended so that the force applied to the armrest 6 in the forward movement direction such as gravity applied to the armrest 6 can be relaxed. .

  In addition to this configuration, when the armrest 6 is moved forward to the seat cushion 2, the rubber member 20 moves to the vicinity of the upper portion of the protrusion 21 by moving one end 20 </ b> A of the rubber member 20 attached to the plate 17. This planar surface abuts on the protrusion 21 of the armrest 6, thereby extending between the skin cover 7 and the fixing means 22.

  In the case of this embodiment, when the armrest 6 is tilted forward, the rubber member 20 is placed between the skin cover 7 and the fixing means 22 so that the planar surface of the rubber member 20 abuts the projection 21. By being provided, the surface of the rubber member 20 can be easily deformed in accordance with the shape of the protrusion 21, and thus the damage of the protrusion 21 can be prevented.

  Thus, the rubber member 20 pulls the skin cover 7 downward due to the tension generated by the extension, and thereby the skin cover between the armrest 6 in the forward-turned state and the opening / closing part 11 (FIG. 2) in the standing state. 7 is bent in a curved shape, and as a result, a force acting in the forward direction is applied to the opening / closing part 11 in the standing state by the skin cover 7 while maintaining the armrest 6 in the forward state. Yes.

  Here, as shown in FIG. 4, the opening / closing part 11 moves forward to the upper surface 6 </ b> A side of the armrest 6 by unlocking the opening / closing part 11 locked in a standing state to the frame member 8 by the unlocking part 30. The distal end portion of the skin fixing screw 16 at the upper end portion 11A can be brought into contact with the upper surface 6A of the armrest 6.

  Actually, in the case of this embodiment, when the opening / closing part 11 is moved forward, even if the tip of the skin fixing screw 16 comes into contact with the upper surface 6A of the armrest 6 due to the force acting in the forward movement direction, Since the tip of the screw 16 is formed in a curved shape, damage to the upper surface 6A of the armrest 6 can be avoided.

  Incidentally, when the pressing surface 33 is pressed down until the guide shaft 31 comes into contact with the bottom of the guide receiving portion 32, the lock releasing portion 30 raises the guide hole upper portion 34 of the lock plate 15 to the uppermost portion of the tapered surface 35. Accordingly, the lowermost end portion 15A of the lock plate 15 rises to a position where it cannot come into contact with the upper end portion 11A of the opening / closing portion 11, and thus the opening / closing portion 11 can be unlocked.

  Therefore, when the pressing surface 33 is released and the lock is released, the opening / closing part 11 can be moved forward by a force applied in the forward movement direction, so that the rubber member 20 is retracted to return to the original length dimension. Has been made.

  As shown in FIG. 5, the rubber member 20, the armrest rubber member 24, the plate 17, and the skin cover 7 are arranged together with the front surface 11B of the opening / closing portion 11 and the armrest when the opening / closing portion 11 and the armrest 6 are in the standing state. Although the rubber member 20 and the armrest rubber member 24 are retracted to return to a substantially straight shape, the plate 17 is formed in a thin plate shape, and the skin cover 7 is folded in two. Since it can be formed as a whole, the thickness can be reduced, and thus the armrest 6 can be securely stored in the trunk through portion 4.

  In the above configuration, the user can bring the armrest 6 forward in the seat cushion 2 by moving the armrest 6 forward, and can make the opening / closing portion 11 stand up in the trunk through portion 4. it can.

  As a result, the rubber member 20 is extended by the projection 21 of the armrest 6 and pulls the skin cover 7 downward, so that a force acting in the forward direction can be applied to the opening / closing part 11.

  At this time, the skin cover 7 is pulled downward by the rubber member 20, and the upper part 6 </ b> A of the armrest 6 from the upper part of the trunk through part 4 is formed in a curved shape, so that it is integrated with the seat cushion 2 and the seat back 3. An appearance can be obtained and an impression can be given to the user as if the opening / closing part 11 does not exist.

  In this state, for example, when performing an opening operation for moving the opening / closing part 11 forward in order to load a long object such as ski in the trunk room, the user presses the pressing surface 33 with the fingertip.

  Thereby, since the force by the rubber member 20 is applied to the opening / closing part 11 in the forward direction by the skin cover 7, the user simply presses the pressing surface 33 and releases the lock, so that the upper surface of the armrest 6 can be released. The opening / closing part 11 can be moved forward to 6A.

  At this time, since the tip end portion of the skin fixing screw 16 is formed in a curved shape, the opening / closing portion 11 can be moved forward without damaging the upper surface 6A of the armrest 6.

  Thus, by moving the opening / closing part 11 forward, the rear trunk room E1 (FIG. 1) and the front passenger compartment E2 can communicate with each other through the trunk through part 4, and a long object is inserted and loaded from the trunk room E1 into the passenger compartment E2. it can.

  As described above, in the present embodiment, corresponding to claim 1, the trunk through portion 4 that is formed in a part of the seat back 3 and communicates between the trunk room E1 and the interior of the passenger compartment E2, and the trunk through portion 4 The armrest 6 is pivotably provided on the lower side of the seat cushion and can be moved forward on the seat cushion 2 and can be pivoted on the lower side of the trunk through portion 4 and can be moved forward and backward on the armrest 6 in the forward-turned state. Part 11, lock plate 15 that locks opening / closing part 11 upright in trunk through part 4, one end attached to armrest 6, and the other end opening / closing part above the lower side of trunk through part 4 11 and equipped with an armrest 6 in a forward-turned state, a skin cover 7 that stretches between an open / closed portion 11 and an unlocking portion 30 that unlocks the lock plate 15. As a result, when the armrest 6 is tilted forward while the opening / closing part 11 is in the upright state, the skin cover 7 is stretched, whereby the force to always move the armrest 6 forward relative to the standing opening / closing part 11 Therefore, the opening / closing part 11 can be easily moved forward simply by releasing the lock of the opening / closing part 11 by the unlocking part 30, thus easily communicating between the trunk room E1 and the interior of the vehicle compartment E2. Can do.

  Further, in this embodiment, corresponding to claim 2, the lower end portion 6B of the armrest 6 is formed with a projection 21 and one end 20A is attached to the skin cover 7 and the other end 20B is the armrest. When the armrest 6 is tilted forward while the opening / closing part 11 is in an upright state, the skin cover 7 and the fixing means 22 are brought into contact with the protrusion 21. When the armrest 6 is tilted forward while the opening / closing part 11 is in an upright state, the skin cover 7 is pulled downward by the rubber member 20 and stretched. As a result, it is possible to always apply a forward force to the armrest 6 side with respect to the standing opening / closing part 11. Thus, the unlocking part 30 can be used to release the opening / closing part 11 by simply unlocking the opening / closing part 11. Easily put forward Can.

  Further, in this embodiment, corresponding to claim 3, the rubber member 20 is formed in a band shape, and when the armrest 6 is tilted forward while the opening / closing part 11 is in an upright state, the planar shape of the rubber member 20 is increased. Since the surface is in contact with the protruding portion 21, the armrest 6 is in an upright state, and even if the rubber member 20 is positioned between the armrest 6 and the opening / closing portion 11, the rubber member 20 does not get in the way. The armrest 6 can be securely stored in the trunk through portion 4 and the planar surface of the rubber member 20 can be easily deformed in accordance with the shape of the protrusion 21, thus damaging the protrusion 21. Can be prevented.

  Further, in this embodiment, corresponding to claim 4, the skin cover 7 is formed so as to cover from the front surface 11B of the opening / closing portion 11 to the upper surface 6A of the armrest 6, so that the opening / closing portion 11 and the armrest 6 are rotated. Since the lower part of the trunk through part 4 provided freely and the entire opening / closing part 11 can be covered with the skin cover 7, the mechanical structure of the opening / closing part 11 and the armrest 6 in the trunk through part 4 can be hidden. Thus, the vehicle trunk-through opening / closing device 5 and the rear seat 3 can be integrated with each other in appearance, and when the armrest 6 is used in a forward-turned state, the user can mechanically use the opening / closing portion 11 or the like.
