Description

Cross type backrest multi-person seat

Technical Field

The utility model relates to a vehicle auxiliary facilities field especially relates to a many people's seat of crossing back.

Background

The seat is an indispensable facility on the public transport means, and generally, all can have the bench on similar subway, waiting room, passenger train, the sightseeing bus of touring, can take many people simultaneously on this kind of bench, but because everybody's size is different, leads to the number of people that can take in every row to be different, and the passenger all can feel crowded under many circumstances, still can lead to the overload problem from this.

The shoulder width of a person is the widest part of the body and is certainly wider than the width of the leg, particularly, because the shoulder is connected with the arm, the arm of a passenger can move when playing a mobile phone, reading a book and the like, once the shoulder part is pressed, the arm can be limited to move, and the movement is difficult.

When the passenger feels a lot of crowding, the passenger usually leans forward, and the purpose of the action is to relieve the crowding feeling of the shoulders. However, the waist of the passenger is not supported at this time, and the passenger may be fatigued after a long-time ride.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the aforesaid current situation, provide a many people's seat of crossing back.

The utility model adopts the technical proposal that: a cross-back multi-person seat comprising: ordinary back, cushion, a plurality of little back mechanism, ordinary back sets up on the cushion, it is a plurality of little back mechanism sets up on the ordinary back, between the little back mechanism ordinary back with the cushion forms first seat, little back mechanism with the cushion forms the second seat, first seat with the crisscross setting of second seat.

The utility model has the effects that: by means of the method of adding the small backrest, the shoulders of adjacent passengers cannot be close together, the riding area is divided, the riding space and the number of passengers are fixed, and the riding comfort is improved.

Drawings

Fig. 1 is a schematic view of the overall structure of a cross-type backrest multi-person seat of the present invention;

fig. 2 is a schematic structural view of a small backrest mechanism in the present invention;

fig. 3 is a schematic sectional view of the small backrest mechanism of the present invention.

Detailed Description

The utility model is described below with the attached drawings:

referring to fig. 1, 2 and 3, a cross-back multi-person seat includes: ordinary back 1, cushion 2, a plurality of little back mechanism, ordinary back 1 sets up on the cushion 2, a plurality of little back mechanism sets up on the ordinary back 1.

Between the little back mechanism ordinary back 1 with cushion 2 forms first seat, little back mechanism with cushion 2 forms the second seat, first seat with the crisscross setting of second seat makes things convenient for the passenger to take the time upper part of the body stagger, makes adjacent passenger's shoulder can not closely be in the same place, promotes and takes the comfort level.

Little back mechanism includes little back 3, rotates piece, locating part, mounting, the mounting with ordinary back 1 is fixed, the locating part cover is established on the mounting, rotate piece one end with little back 3 is fixed, the other end with the mounting is articulated, the locating part is used for the restriction the rotation range of rotating the piece.

The mounting includes bracing piece 4, fixing base 14 sets up on the

ordinary back

1, 4 one ends of bracing piece with fixing base 14 is fixed, the 4 other ends of bracing piece with it is articulated to rotate the piece.

The support rod 4 is provided with a limiting block fixing hole 10.

A small backrest fixing through hole 9 is formed in one end, hinged to the rotating piece, of the supporting rod 4.

The rotation piece includes last rotation support pole 5, lower rotation support pole 7 and little back fixing bolt 16, go up 5 one end of rotation support pole with little back 3 is fixed, has seted up last rotation support pole fixed orifices 6 on the other end, lower rotation support pole 7 one end with little back 3 is fixed, has seted up lower rotation support pole fixed orifices 8 on the other end, little back fixing bolt 16 from the top down wears to locate in proper order go up rotation support pole fixed orifices 6 little back fixing hole 9 reaches rotation support pole fixed orifices 8 down. The small backrest 3 can rotate by taking the small backrest fixing bolt 16 as a rotating shaft. The position of the small backrest 3 in fig. 1 is the working direction, and the small backrest is used as the backrest of the passenger seat. When the small backrest 3 is rotated by 90 degrees about the small backrest fixing latch 16, it is in a storage state and does not occupy a seating space.

Since the small backrest 3 can rotate around a shaft and can sway during operation, it needs to be fixed in the working direction. The locating part includes stopper 11, stopper fixing bolt 12, a slip through-hole has been seted up on the stopper 11, stopper 11 passes through the slip through-hole cover is established on the bracing piece 4, fixing bolt hole 17 has been seted up on the stopper 11, fixing bolt hole 17's direction with the slip through-hole is perpendicular, fixing bolt hole 17 with the slip through-hole switches on, works as stopper 11 slides and makes fixing bolt hole 17 with when stopper fixed orifices 10 aligns, stopper fixing bolt 12 wears to locate fixing bolt hole 17 with stopper fixed orifices 10 realizes stopper 11's fixing. The position of the limiting block fixing hole 10 is such that the limiting block 11 is closely connected with the tail ends of the upper rotating support rod 5 and the lower rotating support rod 7 at the moment, so that the small backrest 3 cannot rotate around the shaft. When the small backrest is required to be stored, the limiting block fixing bolt 12 is pulled upwards to be away from the limiting block fixing hole 10, and meanwhile the limiting block 11 slides to be away from the small backrest 3, namely the small backrest 3 is rotated to realize storage.

In this embodiment, the limiting member further includes a return spring 12, one end of the return spring 12 is connected to the limiting member fixing bolt 12, and the other end is connected to the limiting member 11.

A crossing back many people seat, utilize the method that increases little back, make adjacent passenger's shoulder can not closely be in the same place, will take the region and separate, make and take the space and take the number fixed, promote and take the comfort level.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
