Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat for a vehicle, and more particularly to a locking mechanism for locking a retractable seat cushion to a vehicle body in a raised state.

In general, the seat of a vehicle, such as a movable rear seat of a car, is made so that the seat cushion is raised and then the seat back is pulled down to open the rear hatch of the car and increase the space for storing luggage. There is something. However, conventionally, the seat cushion of such a seat that can be pulled up has not been equipped with a locking mechanism that locks the seat cushion in the raised state.

For this reason, the seat cushion in the raised state is unstable and has the drawback of wobbling or about to topple over due to vibrations or the like while the vehicle is running.

In view of the above-mentioned points, the present invention provides a seat for vehicles etc. equipped with a locking mechanism that can be reliably locked when the seat cushion is pulled up and does not interfere with the structure or appearance of the seat. The purpose is to provide new information.

For this reason, in the vehicle seat of the present invention, a body-side bracket is provided, which consists of a fixing part and a locking part for fixing to the seat mounting part of the vehicle, and the seat is placed between the fixing part and the locking part. a locking mechanism section that is provided with a hinge section to which the side bracket is pivoted, and that locks the seat side bracket in a state where the seat side bracket is fitted to the locking section;
A lock release lever mechanism is provided to release the lock, and the seat cushion can be locked in the raised state.
This lock is released and the seat cushion can be pulled back.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a seat for a vehicle or the like according to the present invention will be described below with reference to the drawings.

This embodiment is an embodiment for a rear seat of a car, and as shown in FIG. Then, pull down the seat bag 2 to the position shown by the dashed line in the figure. As a result, the back surface of the seat bag 2 is connected on the same plane as the floor 3 of the luggage compartment, so that the rear hatch 5 of the automobile 4 can be opened to widen the space for storing luggage.

FIGS. 2 and 3 show the main parts of this seat cushion 1 installed in a vehicle. Reference numeral 6 denotes a body-side bracket formed in a U-shape in cross section, and is composed of a fixing part 6a and a locking part 6b. This fixing portion 6a is fixed to a seat attaching portion 7 of the body floor with screws 8. Also, the fixing part 6 of this body side bracket 6
A hinge part 9 is provided between a and the locking part 6b, and a seat side bracket 11 having a U-shaped cross section is pivoted to a hinge pin 10 of the hinge part 9. Furthermore, this seat side bracket 11 is fixed to the cushion frame 12 of the seat cushion 1. In this example, as shown in FIG. 2, a pair of body-side brackets 6, seat-side brackets 11, etc. are used to move the seat cushion 1 to the position shown by the solid line and the position shown by the dashed-dotted line in FIG. It is mounted so that it can rotate in the direction of arrow A around the hinge part 9 between. Furthermore, when the seat cushion 1 is attached, the locking portion 6b of the body side bracket 6 is configured to be hidden inside the seat cushion 1, and when the seat cushion 1 is rotated, this locking portion 6b is hidden inside the seat cushion 1. A necessary space 13 is provided to prevent the stop portion 6b from hitting the sponge portion or the like within the seat cushion 1.

The locking portion 6b of the body-side bracket 6 and the seat-side bracket 11 are provided with a locking bracket mechanism.

This lock bracket mechanism has a U-shaped cross section at the tip of the locking part 6b of the body side bracket 6, as shown in FIGS. 4A and 4B with the body side bracket 6 and seat side bracket 11 taken out. A side plate 14 is provided so as to close the corner of the end face.
This side plate 14 has a U-shaped locking groove 15.
and a guide surface 16 cut out diagonally so as to guide from the outside of the side plate 14 to the locking groove 15.

Further, a lock bracket 17 is installed on the inner surface of the seat side bracket 11. For this purpose, a shaft pin 18 is provided protruding from the inner surface of the seat side bracket 11. Further, a shaft hole is bored at one end of the rectangular plate-shaped lock bracket 17, and the shaft pin 18 is inserted through this hole. Further, a return spring 19, which is a torsion coil spring, is inserted into the shaft pin 18, and a nut 20 having a retaining structure is screwed onto the return spring 19. One arm 21 of the return spring 19 is engaged with the small stopper hole 22 of the lock bracket 17, and the other arm (not shown) is fixed to the shaft pin 18 fixed to the seat side bracket 11. With this configuration, the lock bracket 17 is always biased in the direction of arrow B.

A through hole 23 is bored in the other end of the lock bracket 17, and one end of a connecting wire 24 connected to the lock release lever mechanism is engaged therewith.

As shown in FIGS. 5A, 5B, and 6, this lock release lever mechanism includes an operating lever 25.
A lever pin 26 is provided at one end, and this lever pin 26 is pivoted to a shaft hole in a fan-shaped recess 29 for housing an operating lever 25 provided on the cushion frame 12, and the lever pin 26 projects from the back surface of the cushion frame 12. It is constructed by fixing the central part of a long plate-shaped arm 27 to the shaft head of the arm. And this wristband 2
Small holes 28, 28 are formed in both ends of the lock release lever mechanism 7, and the other ends of the connecting wires 24, 24, which have one end secured to the lock brackets 17 on the left and right sides of the lock release lever mechanism, are respectively inserted. The small holes 28 and 28 are engaged with each other.

In the vehicle seat of this example configured as described above, when the seat cushion 1 is placed in the seated state, the body side bracket 6, seat side bracket 11, etc. are arranged as shown in FIGS. 3 and 4B. are open to each other. When this seat cushion 1 is raised, the lock bracket 1
7 moves along the guide surface 16 of the side plate 14, and is locked in the locking groove 15 as shown in FIG. 4A by the biasing force of the return spring 19, and the seat cushion 1 is moved along the dashed line in FIG. Lock in the position shown.

Note that in this locked state, lock bracket 1
7 is locked in the locking groove 15, and the seat side bracket 11 is matched with the inner surface of the body side bracket 6 to prevent further rotation, so that it is locked in a fixed position.

Next, when returning the seat cushion 1 to the seated state, the operating lever 25 located at the center of the back surface of the seat cushion 1 is rotated in the direction of arrow C. As a result, the connecting wires 24, 24, which are respectively connected to both ends of the armrest 27, are pulled at the same time, and the lock brackets 17, 17 are disengaged from the locking grooves 15, 15, and the locks are released. The seat cushion 1 can then be pulled back to the seated state.

As detailed above, according to the vehicle seat of the present invention, the locking portion of the body side bracket, the seat side bracket, and the lock bracket mechanism, which constitute the hinge mechanism for pivotally supporting the seat cushion, are provided on the seat cushion. The seat side bracket is fixed to the inner surface of the part of the cushion frame that corresponds to the lower surface of the space, so it does not protrude to the outside of the seat cushion, making it particularly easy to install the seat. When using the compartment as a luggage compartment, even when the seat cushion is flipped up, it does not protrude to the back side at all, so the seat cushion can be flipped up without the luggage hitting, getting caught, or getting caught. In this state, the back side can be effectively used as the front wall of the luggage compartment without any problems.

In addition, when the seat cushion is flipped up, the seat side bracket is fitted into the locking part that is integrated with the fixing part of the body side bracket that is fixed to the body, and is integrated with the locking part, so The seat cushion does not swing or come off even when force is applied from the left and right directions, and the seat cushion is reliably supported in the raised state. The seat cushion can be raised and rotated smoothly at all times without any fear of such problems, and the baggage compartment can be formed extremely easily.
