Description

Seat anti-submergence structure and vehicle

Technical Field

The utility model relates to a car seat, concretely relates to seat prevents dive structure and vehicle.

Background

Currently, safety in the event of a collision in a vehicle is of increasing concern to customers, particularly in the case of second-row passenger safety. Generally, the seat cushion of the second-row seat is thicker than that of the front-row seat due to the whole vehicle arrangement parameters, the comfort of the seat and the like; if the anti-submergence structure is not designed, the passenger can not be supported sufficiently during collision, so that the pelvis of the passenger can be displaced due to submergence and can be separated from the restraint of the safety belt in serious cases.

Referring to fig. 1, the second row of seat cushion usually uses a high-resilience foamed polypropylene material for preventing the seat cushion from sinking, and the foamed polypropylene 9 is fixed inside the seat cushion 8 through a connecting structure 10. However, the foaming polypropylene has high price and needs a special connecting structure, so that the submergence preventing structure has high overall cost and poor economical efficiency. Referring to fig. 2, the anti-dive bracket 5 made of metal plates is directly arranged inside the seat cushion 8 instead of the foamed polypropylene 9, and passengers can feel that obvious foreign body feeling is generated below the seat cushion when the passengers sit due to the high hardness of the metal plates, so that the riding comfort is affected.

Disclosure of Invention

The utility model aims at providing a seat prevents dive structure and vehicle, its simple structure, low cost does not have obvious foreign matter and feels, can give the passenger enough support.

Seat prevent dive structure, including being fixed in the support horizontal pole on the seat skeleton, be fixed with on the support horizontal pole and prevent dive frame, should prevent dive frame and indulge the support rod including an at least horizontal support rod and two at least, indulge support rod front end and horizontal support rod fixed connection, rear end and seat skeleton or support horizontal pole fixed connection.

Further, indulge the bearing pole and include first bearing pole and connect in first bearing pole and the second bearing pole that extends to the back below, first bearing pole front end and horizontal bearing pole fixed connection, second bearing pole rear end and seat skeleton or support horizontal pole fixed connection.

Furthermore, the rear end of a second bearing rod of the longitudinal bearing rod is provided with a connecting section which extends transversely, and the connecting section is welded and fixed with the seat framework or the supporting cross rod.

Furthermore, the number of the longitudinal supporting rods is 2-5.

Furthermore, the number of the longitudinal bearing rods is 2, and the front ends of the two longitudinal bearing rods are respectively fixedly connected with the two ends of the transverse bearing rod.

Furthermore, the front part of the seat framework is fixed with a reversed V-shaped anti-submerging support which is positioned below the plane of the supporting cross rod.

A vehicle comprises a seat, wherein the seat comprises the seat anti-submergence structure.

The utility model discloses on the basis of current support horizontal pole, increase and prevent dive frame and support the horizontal pole and support the passenger jointly, there is not obvious foreign body and feels, improved the travelling comfort of taking to simple structure, low cost.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 7 to 9, the seat anti-dive structure includes two support rails 2 fixed to a seat frame 1, and the two support rails 2 are respectively located at the front and rear portions of the top surface of the seat frame 1. Support and be fixed with on the horizontal pole 2 and prevent dive frame, should prevent dive frame integrated into one piece indulge bearing rod 4 including a horizontal bearing rod 3 and two, indulge bearing rod 4 and include first bearing rod 41 and connect in first bearing rod 41 and the second bearing rod 42 that extends to the rear below, first bearing rod 41 front end and 3 end fixed connection of horizontal bearing rod, anterior and the support horizontal pole welded fastening in the place ahead, second bearing rod 42 rear end is equipped with horizontal extending's linkage segment 43, this linkage segment 43 and the support horizontal pole 2 welded fastening at rear.

In order to further improve the supporting effect of the seat and improve the riding comfort, a reversed V-shaped anti-submerging bracket 5 is fixed at the front part of the seat framework 1, and the anti-submerging bracket 5 is positioned below the plane of the supporting cross rod 2.

Referring to fig. 3, the existing anti-dive structure includes only two support bars 2 fixed to a seat frame 1 and an anti-dive bracket 5, and the anti-dive bracket 5 is located below a plane where the support bars 2 are located, referring to fig. 4, when a dummy 6 is normally seated, a gap 7 exists between a top end extension line 51 of the anti-dive bracket and thigh root and hip axis extensions 61 of the dummy, and the dummy does not sense the presence of a foreign object below due to the existence of the gap 7. Referring to fig. 5, when passing through a bumpy road surface, the dummy 6 may compress the cushion foam to a limit state, and it is seen that the gap 7 is almost 0, that is, the root of the thigh and the hip of the dummy 6 directly contact the anti-dive bracket 5, and the foreign body sensation is significant, affecting the riding comfort.

When adopting the utility model discloses behind the dive frame of preventing, see fig. 10, when through the road surface of jolting, owing to prevent the presence of dive frame, guaranteed that clearance 7 can not compressed the limit, concrete reason is: referring to fig. 11, the extension lines 61 of the thigh root and the hip axis of the dummy are parallel to the longitudinal support rod 4 of the anti-dive frame, i.e. the longitudinal support rod 4 and the thigh root and the hip of the dummy 6 follow the shape, which can provide sufficient support and ensure that the dummy 6 cannot move down continuously. Referring to fig. 12, after the dummy 6 is translated downwards by 100mm, the longitudinal support rod 4 is right above the extension line 61 of the axes of the thigh root and the hip of the dummy, which illustrates that the longitudinal support rod 4 is right below the thigh root and the hip of the dummy 6 in a normal sitting posture; when the dummy 6 moves downwards through a bumpy road surface, the root part of the thigh and the hip part of the dummy 6 are supported by the two longitudinal supporting rods 4, continuous downward movement is avoided, namely, the gap 7 is not compressed to the limit when the dummy 6 passes through the bumpy road surface, the root part of the thigh and the hip part of the dummy 6 are prevented from directly contacting the submergence preventing support 5, no obvious foreign body feeling exists, and riding comfort is improved.

Simultaneously the utility model discloses also solved dummy 6 and taken the obvious problem of foreign matter sense when the cushion is foremost, refer to 6, prevent the dive support 5 of preventing among the dive structure now and need consider intensity temperature itself, the front end has great edge, when the passenger talks with the driver in the second row, dummy 6 takes foremost at the cushion, prevent that the dive structure can't give dummy 6 buttock enough supports now, clearance 7 is 0 almost, the foreign matter sense is obvious. Referring to fig. 13, since the anti-dive frame is added, when the dummy 6 sits on the foremost end of the seat cushion, the transverse support bar 3 at the front end of the anti-dive frame gives the dummy 6 sufficient support to the buttocks, increasing the gap 7, without significant foreign body sensation, improving riding comfort.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
