In addition, at the time of getting on and off the seat, and at the time of use, the side fall prevention portion is provided along the outside surface of the seat entry and exit side, so the outside surface of the seat entry and exit side is protected by the side drop prevention portion Thus, it is possible to prevent deformation of the seat on the side of getting on and off, and also prevent dirt due to contact of the occupant's shoes when getting on.
[0011]
Further, the fall prevention plate is formed of a plate that covers an upper portion of the front side surface of the sheet, and the plate is provided with a grip portion for raising the fall prevention plate. Can be prevented, the appearance quality of the sheet can be improved, and the fall prevention plate can be easily moved up and down.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a passenger seat of a vehicle seat provided with a device for preventing a dropped object according to the present invention. In the drawing, SC indicates a seat cushion, and SB indicates a seat back.
[0013]
On the front side C forming the front side of the seat cushion SC, there is provided a device for preventing a dropped object according to the present invention comprising the drop prevention plate 1.
In the drawing, a is an upper surface that is a seating surface of the seat cushion SC, and B is an outer surface on the getting on and off side. On the left side of FIG. Tall ones are installed.
[0014]
The above-described fall prevention plate 1 is a single synthetic resin plate formed to have a size that covers the upper half of the front side surface c of the seat cushion SC, and a grip portion 14 having a through hole is formed at the center in the left-right direction. When the fingertip is hooked on the grip portion 14 and lifted upward, the fall prevention plate 1 projects upward with respect to the upper surface a of the seat cushion SC as shown by a chain line. It is configured to slide.
[0015]
Further, the fall prevention plate 1 is provided with a side fall prevention portion 1A extending in the outer surface B direction, and a mounting object B mounted on the upper surface of the seat cushion SC as shown by a chain line in FIGS. Of the seat cushion SC from the side.
[0016]
The side drop prevention portion 1A is formed along the outer surface B of the seat cushion SC, and as shown by a solid line in FIGS. The corner between side c is protected.
[0017]
The fall prevention plate 1 is attached to a pair of left and right stays 10 and 10 so as to be freely slidable in the vertical direction. The stays 10 and 10 have base ends welded to a fixed plate 16, and the fixed plate 16 is a seat cushion as shown in FIG. Fastened to the cushion frame 3 constituting the SC.
[0018]
In FIG. 3, reference numeral 4 denotes a back frame constituting the seat back SB, reference numeral 20 denotes a lower rail of a slide rail for adjusting the front / rear position of the seat, reference numeral 21 denotes the same upper rail, respectively, and left and right upper rails 21 and 21 sides. Is provided with a U-shaped lock release operation lever 22. By operating this operation lever 22, the lock of the upper rails 21 and 21 to the lower rail 20 is released.
[0019]
The operation lever 22 described above is disposed below the front side C of the seat cushion SC, and a cutout portion is provided below the fall prevention plate 1 so that the operation lever 22 can be operated.
[0020]
The stays 10 and 10 are formed in a U-shape, and the tips 11 and 11 of the stays 10 and 10 are upwardly oriented at substantially right angles, and are formed in multiple stages in the vertical direction. Are provided in large numbers.
The tips 11, 11 of the stays 10, 10 are inserted into resin holders 12, 12, as shown in FIG. 4, and each holder 12 is mounted in a locking cylinder 13 embedded in the fall prevention plate 1. Is done. The left and right locking cylinders 13 are integrally connected by a connecting piece 15, and the locking projections 12A of the holder 12 are engaged with the locking holes 13A provided in the locking cylinder 13, whereby the holder 12 is fixed. A locking spring 18 is attached to a slit 12B provided at the lower end of the stay 12, and the locking spring 18 engages with a locking groove 11A provided at the distal end 11 of the stay 10, so that the fall prevention plate 1 The structure is such that the height is kept constant. The shape of each locking groove 11A is formed so that the upper and lower portions are inclined so that the fall prevention plate 1 can move up and down. Reference numeral 13B in the figure indicates a fixing piece for fixing the locking cylinder 13 in the fall prevention plate 1.
[0021]
Since the fall prevention plate 1 is configured as described above, when the object B such as luggage is placed on the front passenger seat, the fingertip is hooked on the grip portion 14 and lifted upward, thereby increasing the seat cushion SC. The fall prevention plate 1 disposed below the upper surface a of the seat cushion SC projects together with the side fall prevention unit 1A above the upper surface a of the seat cushion SC.
[0022]
At this time, the fall prevention plate 1 is adjusted to be high according to the size (height) of the object B to completely prevent the object B from falling.
[0023]
When the occupant sits on the passenger seat without placing the object B, the fall prevention plate 1 is pushed down and used along the front side C and the outer side B of the seat cushion SC. When the fall prevention plate 1 is lowered, the stays 10, 10 and the like are covered with the fall prevention plate 1 so as not to be exposed to the outside, thereby improving the appearance quality of the sheet. .
[0024]
【The invention's effect】
According to the first aspect of the present invention, it is possible to prevent the placed object, in particular, small articles from falling from the side of the seat cushion by the side drop prevention portion.
In addition, the side fall prevention portion is disposed along the outside surface of the seat cushion on the entry / exit side when the fall prevention plate is not used, and thus holds the outside surface of the seat cushion. Therefore, at the time of getting on and off, the outer surface of the seat cushion is not stained or damaged by contact with the occupant's shoes or the like.
[0025]
In addition, since the corner between the front side surface and the outer side surface of the seat cushion and the front side of the outer portion are supported by the side drop prevention portions, deformation of the foam pad and the like constituting the seat cushion can be prevented.
[0026]
According to the second aspect of the present invention, it is easy to perform the vertical sliding operation of the fall prevention plate by the grip portion.
Further, by forming the fall prevention plate with a plate covering the upper part of the front side surface of the sheet, the appearance quality of the sheet can be improved.
