Description

Automatically turn down automotive seat
Technical field
The present invention relates to a kind of automotive seat, especially a kind of automotive seat that can automatically turn down.
Background technology
The passage of microvan second row of seats one side is added with a Collapsible seat usually, Collapsible seat can be opened when the passenger is many and make in car to increase a seat, can be by folding perpendicular second row of seats one side that leans against of folding seat when the passenger is few, or the 3rd the passenger of row on seat be the passage of abdicating the 3rd row's seat passenger getting off car need to get off the time, also need folding the erecting of folding seat leaned against to second row of seats one side, in order to abdicate the passage of the 3rd row's seat passenger getting off car.Current this folding seat is when needs are folding, after being sitting in passenger on this folding seat and standing up, first to manually backrest be folded to equal with cushion, by the passenger, hand is reached to seat bottom and rotate release lever, firmly folding seat integral body made progress again and, after infolding, folding the erecting of folding seat could be leaned against to second row of seats one side.This folding seat has the following disadvantages: need fold manually, the integrated automation degree is not high, because the release lever position is hidden, operate extremely inconvenient, can bring more how inconvenience for the passenger who is unfamiliar with the car inner structure, in addition when emergency episode occurs, after the passenger who is sitting in passage limit Collapsible seat stands up to withdraw, because Collapsible seat can not auto-folder, can not give timely to be sitting in row's passenger thereafter and to abdicate passage.At present, also have in the industry some can realize the automotive seat of turnover automatically, but its major part all exist complex structure, high in cost of production defect.
Summary of the invention
The purpose of this invention is to provide a kind of automatic turnover automotive seat that can realize automatic turnover.
The technical scheme that the present invention adopts for achieving the above object is: a kind of automatic turnover automotive seat, these automotive seat comprise and adding by the frame pipe, add by connecting panel, add base frame tube, add a transverse tube, seat is by connecting panel, add by connecting panel and be fixedly connected on respectively two ends that add by frame pipe bottom side, add a transverse tube and be connected to the two end inboards that add base frame tube, seat by connecting panel respectively by bolt with add base frame tube, the mounting hole added by connecting panel connects, seat by connecting panel and add by between connecting panel, be provided with add by the frame pipe be not subject to external force when pushing make to add by the frame pipe can be automatically the folding backrest response agency added on base frame tube that leans against forward, add base frame tube one side and be connected with the connecting panel I that adds to its inboard extension, add a transverse tube and add a connecting panel I opposite position inboard and be connected with and add a connecting panel II, add a connecting panel I and add a connecting panel II and be connected with respectively the L shaped strut bar to the backward outer bending of downward-extension, the intersegmental turnover cross bar that is connected with of two L shaped strut bar outwards, two L shaped strut bars with add a connecting panel I, adding between a connecting panel II turnover cross bar be provided with between two L shaped strut bars is not subject to external force when pushing that two L shaped strut bars can make progress automatically to fold to lean against the upset response agency added on base frame tube, base frame tube one side that adds above two L shaped strut bars is connected with two contiguous blocks, be connected with connecting rod between two contiguous blocks, be connected with the push rod of connecting rod swing relatively on connecting rod, both sides, push rod below are respectively arranged with chute, the chute of both sides lays respectively at the upside of turnover cross bar, the adapter shaft two ends of push rod bottom are respectively equipped with the bearing that can roll in chute, two chute bottoms also are provided with the release rotating shaft parallel with adapter shaft, be vertically connected on the solution lock support in the release rotating shaft and be connected to the release spring of release rotating shaft upper support solution lock support, when the adapter shaft of separating lock support and push rod bottom holds mutually, push rod is holded up, the bearing of adapter shaft both sides, push rod bottom is pressed on chute on the turnover cross bar between two L shaped strut bars, the turnover cross bar is stressed to be propped up two L shaped strut bars to be supported on to add base frame tube and adds a transverse tube bottom, after turning the adapter shaft of separating lock support release push rod bottom in the release rotating shaft, the bearing at adapter shaft two ends inwardly rolls in chute, push rod is with the bearing introversion at adapter shaft two ends, the chute at two ends discharges the turnover cross bar, the upset response agency drives automatic upwards folding the leaning against of two L shaped strut bars and adds base frame tube one side.
Further technical scheme of the present invention is: at release rotating shaft one end, extend and be provided with release lever, the release rotating shaft other end is fixedly connected with the release connecting rod, release connecting rod inboard be connected with that an end is connected with it and the other end with add the drag-line be connected by connecting panel, adding by frame pipe folding leaning against while adding on base frame tube forward, drag-line inwardly draws the drive release rotating shaft of release connecting rod and separates in lock support and turns, and turns and separates the adapter shaft that lock support discharges the push rod bottom.
Further technical scheme more of the present invention is: be connected with the drag-line limiting stopper outside adding a transverse tube, described drag-line is fixedly connected on release connecting rod inboard through drag-line limiting stopper one end, and the other end is fixedly connected on and adds by connecting panel.
Further technical scheme of the present invention is: in the L shaped strut bar outer rim near adding by connecting panel one side, be connected with the drag-line locating piece that passes and locate drag-line for drag-line.
Further technical scheme of the present invention is: described backrest response agency is for being connected to seat by connecting panel and adding by assembling bolt I between connecting panel and pull back spring I, seat leans on connecting panel and adds by connecting panel and is respectively equipped with assembling bolt mounting hole I and location hole of the spring I, the assembling bolt I is arranged in assembling bolt mounting hole I through after the pull back spring I again, and two free ends of pull back spring I are located respectively and are present by connecting panel and add by connecting panel location hole of the spring I.
