Abstract
A gear position device for a foldable seat is disclosed. The main body of the gear position device is fixed below a seat armrest and arranged with at least two positioning grooves. The hinge joint of a front and a rear supporting feet of the seat is provided with a fulcrum. The utility model is characterized in that the main body of the gear position device is provided with a downward open groove and also with at least two corresponding positioning channels on two inner side surfaces thereof. The front and the rear supporting feet of the seat are connected with two connecting pieces that are hinged via a rotary shaft, the connecting piece positioned at the outer end is provided with the fulcrum for positioning. Since the positioning channels of the utility model are arranged on the inner side surfaces of the main body of the gear position device, the hand cannot stretch in when the seat is folded or the open angle of the seat is adjusted, thereby rendering more safety with the usage of the gear position device for the foldable seat.
Description
Technical field
The utility model relates to the parts of rumble seat, particularly a kind of gear device of rumble seat.
Background technology
Usually the rumble seat that has gear, its armrest below is provided with the gear sheet, is provided with some flutings that are used to locate the seat open angle in the gear sheet, and fluting is the through hole shape.The hinged place of seat back and front supporting pin is provided with fulcrum.During use, fulcrum is positioned in the different flutings, just can locatees the open angle of seat.But the seat gear device of said structure has the following disadvantages:
1, when folding or conversion seat open angle, because the fluting of the through hole shape in the gear sheet directly exposes, staff is easy to stretch in the fluting, and the user is easy to slander hand in the process of conversion chair angle.
2, the installation of the seat back and front supporting pin of said structure and between centers with is connected inconvenience.
Summary of the invention:
The utility model purpose is: the gear device that a kind of safe in utilization, easily manufactured rumble seat is provided.The utility model is achieved through the following technical solutions:
A kind of gear device of rumble seat, the gear apparatus main body is fixed in the below of armrest, is provided with at least 2 locating slots in the gear apparatus main body, and the hinged place of the back and front supporting pin of seat is provided with fulcrum; It is characterized in that: described gear apparatus main body is provided with downward fluting, two inner surfaces of gear apparatus main body are provided with the location conduit of at least 2 correspondences, the back and front supporting pin of seat links to each other by connector respectively, be hinged by rotating shaft between two connectors, the connector of being located at the outer end is provided with the fulcrum that is used to locate.
Because the utility model location conduit is located at the inner surface of gear apparatus main body, when folding or conversion seat open angle, staff can not stretch in the conduit of location, makes the gear device of rumble seat use safer.And the utility model can be installed in the below of armrest very easily.Because the connector of being located at the outer end is provided with the fulcrum that is used to locate, and is hinged by rotating shaft between two connectors, make a seat back and front supporting pin and a between centers installation be connected all very convenient.
In the utility model, two inner surfaces of described gear apparatus main body are provided with the reinforcement of location conduit.It can make locating slot more firm.
In the utility model, be provided with for being located at the socket that inboard connector inserts in the described connector of being located at the outer end.It can make inboard connector be hinged with outer end connection easily.
In the utility model, described gear apparatus main body and connector are made by plastics.It is easily manufactured, and cost is low.
