Abstract

PURPOSE:To allow a crew to get on or off a car smoothly keeping out of the way by configurating one side of a side frame in such a manner that it is made to be rotational against a seat frame allowing it to be locked in a stand-up condition only when the crew takes a seat. CONSTITUTION:On the load being applied to an upheval (a) on one side of a seat cushion Sc while a crew is taking a seat, a side frame 3 is allowed to be knocked down outside overcoming the resistance of a torsional coil spring 9. This permits the upheaval (a) to be on the same surface of the center section of the seat cushion Sc allowing the crew to sit down on the seat as usual. In this case, the weight of the crew causes a pad pulling bar 19 to be deflected downward allowing an engaging plate 14 to swing counterclockwise with center at the shaft pin 15, since the engaging plate is connected with the end 18a of the pad pulling bar. Subsequently, an engaging pin 16 comes in contact with an engaging projection 12 on a plate 3a of the side frame 3 which is in a stand-up condition. Then the plate 3a is supported by both the engaging pin 16 and a flange section 11 allowing the rotational rame 3 to be locked in a stand-up condition.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a packet sheet installed in a motor vehicle, particularly a smart motor vehicle.

[Conventional technology]

In recent years, there have been many so-called 4-ket seats in automobile seats, in which both sides of the seat cushion and the seat cushion are formed with ridges, and these ridges support the seated person's body from both sides. It has been adopted.

Conventionally, this type of packet seat is constructed by fixing raised side frames to both sides of a seat frame, and covering the peripheries with a pad and a skin material.

[Problem that the invention seeks to solve]

However, with such conventional packet seats, both side frames are completely fixed to the seat frame, so when getting on and off, the thighs etc. come into contact with the raised part and the side frame feels like a foreign body. The present invention has been made in view of this problem, and has the disadvantage that it becomes an obstacle and prevents smooth getting on and off. The purpose is to provide a packet sheet that can be used for

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention attaches one side frame (31) to the cushion frame (1) K so that it can rise and fall freely, and a biasing member (9) such as a torsion coil spring is fitted into this attachment part. The side frame (3) is always made to stand up with respect to the cushion frame (1), and the pad receiving member a &
A locking member I is connected to the side frame (3) and locks the side frame (3) in an upright state when the four-way receiving member (181) is bent downward due to the load of a seated person.

[Effect]

The invention works as follows.

When a passenger gets on and off, the side frame (3) is easily collapsed outward, so that the raised portion aK side frame (
3), passengers can get on and off smoothly without feeling a foreign body sensation, and when the passenger takes a seat, the pad receiving member a& bends downward due to the passenger's weight, and this causes the locking member (14 to operate and lock the side The frame (3) is locked in an upright position, so that the occupant can feel a comfortable hold due to the raised portion a.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, (1) is a cushion frame, and side frames (2) and (3) formed in a substantially U-shape from I4 tube-shaped materials are located on both sides (la) and (lb) of this cushion frame (1), respectively. The pads (4) are arranged symmetrically on both sides, around the frame (21 (31) and on the upper surface of the cushion frame (1), and wadding (5) is arranged on the surface of the cushion frame (1). and epidermis (6)
is covered to form a seat cushion Sc,
Protrusions a are formed on both sides of the frame, following the bulging shape of both side frames (21(3)).

These 7 side frames (2) and (3) are such that the side frame (2) on one side is fixed at both ends to the side surface (1a) of the cushion frame (1) by welding or the like; The other side frame (3) is pivotally supported by the cushion frame (1) so as to be rotatable up and down.

That is, this side frame (3) (hereinafter referred to as a movable frame) has its front end bent nine times backwards and is pivotally supported by a bracket (7) protruding from the side surface (lb) of the cushion frame (1). The rear end portion is formed into a flat plate shape, and the rear end plate portion (3a) has an axis attached to the front facing surface portion (1b) of the step portion formed on the side surface portion (lb) of the cushion frame (1). It is pivoted by a pin (8).

A screw coil spring (9) as a biasing member is inserted into this shaft pin (8), one end of which is attached to the movable frame (3) side, and the other end is attached to the cushion 7 frame (1).
) side, thereby biasing the movable frame (3) in a direction in which it always stands up with respect to the cushion frame (1).

In addition, the tip half of the plate-like part (3a) of the movable frame (3) is inserted into the window hole (1 (B) formed in the side part (1b) of the cushion frame (1), and the outside thereof The upright angle of the movable frame (3) is regulated by the end edge coming into contact with a cut and raised piece aυ formed outward at the lower edge of the window hole 00).

Furthermore, a locking protrusion (121) is formed on the inner edge of the plate-shaped portion (3a), with which a locking pin of a locking member to be described later comes into contact.

A bracket α3 is fixed downward to the inside of the upper surface of the side surface (1b) of the cushion frame (1) in correspondence with the plate-shaped portion (3a) of the movable frame (3). (2 pieces) (A 13K locking member I is pivotally supported in the inner and outer directions by a shaft pin α9 at its center. This locking member I is bent in a dogleg shape, and its outer side The end portion (14a) K is the plate-shaped portion (3a) of the movable frame (3).
1, a locking pin /αe is provided protrudingly, and this outer end (
The inner end (14b) formed by twisting horizontally with respect to the cushion frame (1)
la) (1b) It is connected by a clip member a9 to an end (18a) of a pad receiving member a& stretched across a support spring aη.

In the packet seat of this example configured as described above, when no occupant is seated, the movable frame (3) is in an upright state with respect to the cushion frame (1) due to the biasing force of the torsion coil spring (9). In addition, the locking member (141 has an outer end (14a) inclined downward, and the system locking pin (161) has a plate-shaped portion (3a) of the movable frame (3).
) (see solid line in Figure 1).

When an occupant gets in the vehicle from this state and a load is applied from the occupant's buttocks or thighs to the raised portion a on one side of the seat cushion Sc due to the sitting motion, the movable frame (3) deflects the screw coil spring (9). The raised portion a of the seat cushion Sc is collapsed outwardly against the force.
Since the seating surface is approximately the same as the central portion, the occupant can sit without any trouble (see the dashed line in the same figure).

In this seated state, the reed hood receiving member (181) is bent downward due to the weight of the occupant, so that the locking member α4 connected to the end portion (18a) of the reed hood receiving member (181) is
is rotated in the direction of the arrow about is fixedly held by the locking pin ae and the cut-and-raised piece αυ from both sides, and the movable frame (3) is locked in its upright state so that it cannot rotate. It is comfortably held by the raised portion a (see the two-dot chain line in the same figure).

Furthermore, when the occupant leaves the seat from this state, the i4 dowel receiving member (181) is returned to its original height position by the elastic restoring force of the support spring 1n, and the locking member I is rotated in the opposite direction of the arrow. Since the locking pin (161 is moved away from the locking protrusion (121), the movable frame (
3) can be rotated again, and when the occupant's thigh etc. come into contact with the protrusion a, the movable frame (3) is lowered in the same manner as described above, so the occupant can get off the vehicle without any hindrance. I can do it.

As described above, according to the packet seat of this example, since the raised portion a on one side is laid down when getting on and off, the occupant can smoothly get on and off without feeling the sensation of a foreign body in the side frame (3). Moreover, since the side frames (3) are locked so that they cannot fall down when the seat is seated, a comfortable holding feeling can be obtained by the raised portions a on both sides as in the conventional case.

In this embodiment, only one side frame (3) can be raised or lowered, but 7 frames (2) on both sides
It goes without saying that (3) may also be able to rise and fall.

Further, the present invention is not limited to the seat cushion of the embodiment, but can also be applied to a seat back.

〔Effect of the invention〕

As described above, according to the packet seat of the present invention, one of the side frames can be folded down relative to the seat frame, so when getting on and off, the user does not feel the feeling of a foreign body due to the side frame on the raised part, and the rider can get on and off smoothly. Moreover, since the side frame is locked in the upright position when seated, the holdability of the raised part is completely maintained (compared to conventional models). The effect is significant.
