Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a back seat for a rear seat of a vehicle.

(Prior art) The conventionally known Japanese Utility Model Application Publication No. 57-118763 consists of a seat part and a backrest part provided on the rear side of the seat part, and the backrest part is a single piece in the axle direction. A rear seat for an automobile that is formed on a long fixed backrest part, has an armrest in the center of the fixed backrest part that can be rotated forward, can be moved up and down when folded forward, and can be fixed at an arbitrary height. It is written about.

Also, in the conventionally known Utility Model Application No. 58-59630,
In a vehicle in which a rear seat of a vehicle in which a vehicle interior and a trunk room communicate with each other is formed of a seat part and a backrest part provided on the rear side of the seat part, the backrest part is
Consisting of fixed backrests arranged at intervals in the axle direction and a movable backrest that fills in between the fixed backrests, the movable backrest can be rotated forward, cannot be moved up and down, and has a height. A non-adjustable rear seatback seat for a vehicle is described.

(Problems to be Solved by the Invention) The device described in the above-mentioned Japanese Utility Model Application Publication No. 57-118763 is a device in which the armrest can be rotated forward and vertically movable in the forward position. Since it is fixed, it cannot be stored across the passenger compartment and trunk room. Also, the height of the backrest cannot be adjusted. Furthermore, even if the baggage can be loaded by folding down the backrest, it cannot be loaded because the backrest cannot be folded down.

In addition, the movable backrest described in the conventionally known Japanese Utility Model Publication No. 58-59630 allows only the middle part to be rotated forward, leaving the upper part, and cannot be adjusted up or down, nor can the height be adjusted. Even if the movable backrest is tilted forward, the fixed upper backrest remains above, which obstructs the loading of large items. Furthermore, even if a long object is hung from the passenger compartment into the trunk, the long object will be placed on top of the folded movable backrest, making it unstable against vibrations. In addition, in vehicles with a trunk through mechanism, it is desirable to hide the interior of the trunk from view, but since the movable backrest cannot be moved up or down, it is necessary to move the movable backrest upward to prevent the inside of the trunk from being seen. I can't do it either.

(Objective of the Invention) The present invention allows long items to be stored indoors in a stable state, allows adjustment of the seating position, and allows the interior of the trunk of a vehicle with a trunk through mechanism to be hidden from view. Moreover, it is designed to be able to carry even large amounts of luggage.

A movable backrest part 7 that fills the space between the backrest parts 5 and 6, and a vertical guide sliding member is provided at one of the mating parts of the fixed backrest parts 5 and 6 and the movable backrest part 7. A plate 24 is fixed, a guide rail 8 that slides in the longitudinal direction is engaged with the guide sliding plate 24, and a projecting elastic member 27 is attached to either the guide sliding plate 24 or the guide rail 8. A plurality of engagement grooves 26 are formed at intervals in the longitudinal direction in which the protruding elastic member 27 engages, and the movable backrest portion 7 is connected to the fixed backrest portion 5.6 of the movable backrest portion 7. A recess 10 capable of accommodating the guide sliding plate 24 and the guide rail 8 is formed in at least one of the mating parts, and the movable backrest part 7 has a recess 10 in which the guide sliding plate 24 or the guide rail 8 can be accommodated. The lower part of either one is fixed by the shaft 14,
A backrest seat for a rear seat of a vehicle, in which a locking mechanism consisting of a locking rod 12 and a lock receiving part 11 is provided between the movable backrest part 47 and either the guide sliding plate 24 or the guide rail 8. This is what I did.

(Structure of an Embodiment) The structure of an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a vehicle body, which has a front seat, a rear seat 2, and a trunk room 30 communicating with the vehicle interior.

The rear seat 2 is formed of a seat portion 3 and a backrest portion 4, and the backrest portion 4 includes fixed backrest portions 5, 6 and fixed backrest portions 5 arranged at intervals in the vehicle width direction. , 6, and a movable backrest 7 that fills the spaces between the two.

The movable backrest part 7 has a guide rail 8 and a bearing part 9 on one or both sides thereof, as shown in FIG.
An attachment recess 10 for attaching is formed. The recess 10 is open on the rear side, but not on the front side.

The cross-sectional shape of the guide rail 8 is a substantially C-shaped vertical tube, and a plurality of engagement grooves 26 are formed at predetermined intervals in the height direction at the cut end thereof, as shown in FIG.

A lock receiver 11 having a vertical engagement hole 13 with which an engagement lock rod 12 engages from above is fixed to the upper side of the guide rail 8, and the lower side of the guide rail 8 is fixed to the upper side of the guide rail 8. It is rotatably attached to the movable backrest 7 side.

The bearing portion 9 has a U-shaped side surface as shown in FIG. 5, and has projecting edges 15, 15 at both upper and lower ends thereof, and a vertical bearing hole 16 into which the locking rod 12 is inserted. , 16.

The bearing portion 9 is fixed to the movable backrest portion 7 with a screw 17.

The lower end 19 of the lock rod 12 projects downward from the lower protruding edge 15 through the bearing hole 16, and a collar 22 is fixed between the upper and lower protruding edges 15, 15.
A coil spring 18 is interposed between the collar 22 and the upper protrusion 15 to constantly urge the lock rod 12 downward. A knob 21 is provided at the upper end 20 of the lock rod 12. The lock rod 12 passes through a guide tube 23 attached to the upper part of the movable backrest 7 and is exposed at the upper part of the movable backrest 7.

The fixed backrest portion 5 includes a square-shaped guide sliding plate 2.

25, and when the movable backrest portion 7 is moved up and down, a projecting elastic member 27 selectively engages and holds an engagement groove 26 formed in the guide rail 8. Installed. The guide rails 8 are normally provided on both sides of the movable backrest 7, but as shown in FIG.
It may also have a structure in which the ends of 4 are engaged.

Reference numeral 29 denotes a storage toilet formed on the back side of the movable backrest portion 7.

(Effect of Example) Next, we will discuss the effect.

(1) Operation of folding the movable backrest 7 forward FIG. 2 shows a state in which one side is folded forward.
That is, the knob 2 protruding from the upper part of the movable backrest 7
1, the lock rod 12 moves upward against the elasticity of the spring 18, and the lower end 19 moves against the lock receiver 11 fixed to the guide rail 8, which remains stationary relative to the fixed backrest 5. It comes out of the engagement hole 13, and the engagement with the fixed backrest part 5 is released. In this state, when the movable backrest 7 is manually tilted forward, the movable backrest 7 rotates around the shaft 14 and is folded forward.

In this state, the movable backrest portion 7 does not tilt forward leaving the upper fixed backrest portion as in the known example, but the movable backrest portion 7 as a whole falls forward, so the upper portion of the movable backrest portion 7 is in an open state. This allows large luggage to be easily stored across the vehicle interior and the trunk room 30, which are in communication with each other.

(2) Erecting action of the movable backrest 7 When the movable backrest 7 is raised while pulling the knob 21 protruding to the front of the movable backrest 7 against the elasticity of the spring 18, the locking rod 12 The lower end portion 19 of the lock receiving portion 1 is fixed to the guide rail 8 which is fixed in position with respect to the fixed backrest portion 5.
It faces above the engagement hole 13 of No. 1. When the knob 21 is released in this state, the lower end 19 of the lock rod 12 engages with the engagement hole 13 of the lock receiver 11 fixed to the fixed backrest 5 side due to the elasticity of the spring 18, and The stand portion 7 is maintained in its upright position.

In this state, it becomes a normal rear seat and is used normally.

(3) For vertical movement of the movable backrest 7 When the lower end of the movable backrest 7 is held up in the upright position and pulled upward, the guide rail 8 fixed to the movable backrest 7 is fixed to the fixed backrest 5. It moves upward while being guided by the guide sliding plate 24. The protruding elastic member 27 of the guide sliding plate 24 is engaged with the engagement groove 26 of the guide rail 8 and stopped. In addition, even when the movable backrest 7 has been moved upward, the knob 21 protruding from the top of the movable backrest 7 is pulled up, and the locking rod 1 is locked.
When the movable backrest 7 is disengaged from the lock receiver 11, the movable backrest 7 can be tilted forward about the shaft 14.

In this state, a gap is formed at the lower part of the raised movable backrest 7, so that a long object such as skis can be pushed into the cabin from the trunk room 30 side and stored in the gap. In addition, by pulling up the movable backrest 7, the trunk compartment 3
It is also possible to make 0 invisible. Moreover, when the movable backrest part 7 is moved up and then folded forward, the articles placed on the seat part 3 are held down from above and transported in a stable state.

(Effects) The device described in the above-mentioned Japanese Utility Model Publication No. 57-118763 is a device in which the armrest can be rotated forward and vertically movable in the forward position, but the backrest is fixed. It cannot be stored across the passenger compartment and trunk. Also, the height of the backrest cannot be adjusted. Further, even if the baggage can be loaded by folding down the backrest, it cannot be loaded because the backrest cannot be folded down.

In addition, the movable backrest described in the conventionally known Japanese Utility Model Publication No. 58-59630 allows only the middle part to be rotated forward, leaving the upper part, and cannot be adjusted up or down, nor can the height be adjusted. Even if the movable backrest section is tilted forward, the upper fixed backrest section 4 remains above, which obstructs the loading of large items. Furthermore, even if a long object is hung from the passenger compartment into the trunk, the long object will be placed on top of the folded movable backrest, making it unstable against vibrations. In addition, in vehicles with a trunk through mechanism, it is desirable to hide the interior of the trunk from view, but since the movable backrest cannot be moved up or down, it is necessary to move the movable backrest upward to prevent the inside of the trunk from being seen. I can't do it either.

However, the present invention provides a rear seat 2 of a vehicle in which a vehicle interior and a trunk room 30 communicate with each other, in which the rear seat 2 is formed of a seat part 3 and a backrest part 4 provided on the rear side of the seat part 3. The canopy section 4 is composed of fixed backrest sections 5 and 6 arranged at intervals in the vehicle width direction and a movable backrest section 7 that fills the gap between the fixed backrest sections 5 and 6. A vertical guide sliding plate 24 is fixed to one of the mating parts of 5 and 6 and the movable backrest 7, and a guide rail 8 that slides in the longitudinal direction is fixed to the guide sliding plate 24. The guide sliding plate 24 and the guide rail 8 have a protruding elastic member 27 on one of them, and an engagement groove for the protruding elastic member 27 on the other with an interval in the longitudinal direction. A plurality of engagement grooves 26 are formed in the fixed backrest portions 5 and 6 of the movable backrest portion 7.
A recess 10 capable of accommodating the guide sliding plate 24 and the guide rail 8 is formed in at least one of the mating portions of the movable backrest 7.
The lower part of either the guide sliding plate 24 or the guide rail 8 is fixed by a shaft 14, and the movable backrest 7 and either the guide sliding plate 24 or the guide rail 8 are connected to each other. Since it is used as a backrest seat for a rear seat of a vehicle, in which a locking mechanism consisting of a locking rod 12 and a lock receiving part 11 is provided between the movable backrest parts 7 and the known examples, the entire movable backrest part 7 can be folded forward. Since it rotates, the top is opened after the rotation, and large luggage can be loaded from the passenger compartment to the trunk room 30.

Further, since the movable backrest portion 7 is vertically movable in the standing state, the sitting position can be adjusted.

Furthermore, since the movable backrest 7 is movable up and down in the upright state, long objects such as skis and fishing rods can be loaded in vehicles with a trunk-through mechanism without being visible inside the trunk. .

Furthermore, since the movable backrest 7 can be fixed at any height, a long object such as a ski or a fishing rod can be inserted into the gap where the movable backrest 7 has been moved upward, and then the movable backrest 7 can be fixed at any height. By lowering and holding down the movable backrest 7, the vehicle can be transported in a stable state even if there is vibration during operation.

When the movable backrest part 7 is moved upward and then tilted forward, the lower surface of the movable backrest part 7 can hold down the article placed on the seat part 3, and the article can be transported in a stable state.

A vertical guide sliding plate 24 is fixed to one of the mating parts of the fixed backrest parts 5 and 6 and the movable backrest part 7, and the guide sliding plate 24
A guide rail 8 that slides in the longitudinal direction is engaged with the guide rail 8, and a protruding elastic member 27 is arranged on one of the guide sliding plate 24 and the guide rail 8, and a protruding elastic member 27 is arranged on the other one at a distance in the longitudinal direction. Since the plurality of engagement grooves 26 into which the protruding elastic members 27 engage are formed, it can be implemented with a simple structure.

The guide sliding plate 24 and the guide rail 8 are provided on at least one of the mating portions of the movable backrest portion 7 with the fixed backrest portions 5 and 6.
Since the recess 10 is formed to accommodate the mechanism, the mechanism is not exposed to the front.

The movable backrest portion 7 is provided with the guide sliding plate 24.
Alternatively, the lower part of either one of the guide rails 8 is fixed by a shaft 14, and the movable backrest portion 7 and the front guide sliding plate 24 or the guide rail 8 are fixed.
Since this is a backrest seat for a rear seat of a vehicle, a locking mechanism consisting of a locking rod 12 and a lock receiving part 11 is provided between the seat and either one of the seats. Since it is supported, wobbling can be prevented.

This effect is achieved.
