It is docked with seat frame in-flanges.In seat frame side plate bottom plate with by the transition junction of dorsal plate, seat frame side plate bottom plate is divided into two
Element branches connect the different piece of backrest, and connection is more secured.
The both ends of above-mentioned backrest sheer pole are streamlined respectively to be extended to the corresponding backrest in-flanges, and simultaneously with it is right
The connecting bottom board answered is fixedly connected with backrest in-flanges.Connection using this structure backrest sheer pole and interconnecting piece more securely may be used
It leans on, and shape is more attractive.
The back side of above-mentioned backrest sheer pole is provided along its length the weight loss groove of bar shaped, and the length of the weight loss groove is less than etc.
Spacing between the interconnecting piece at backrest sheer pole both ends.Be conducive to mitigate the weight of backrest using this structure.
It is connected with backrest reinforcing rib between above-mentioned backrest in-flanges and backrest flanging.Be conducive to be promoted using this structure and lean on
The intensity of the back of the body.
It is connected with seat frame reinforcing rib between above-mentioned seat frame in-flanges and seat frame flanging.Upgrade block is conducive to using this structure
The intensity of frame.
From its both ends to middle part direction, gradually concave shape is arcuately curved portion to above-mentioned backrest sheer pole backward.Using this structure
More meet body mechanics, is conducive to improve riding comfort.
Advantageous effect：Using the utility model has the beneficial effects that passing through the transition company in seat frame, backrest, sheer pole three
Meet place and be provided with an interconnecting piece, the interconnecting piece in recess backward, such connection type with it is traditional by reinforce thickness come
The mode for promoting intensity is compared, and can not only effectively mitigate seat-weight, while being also avoided that junction part material heap is blocked up, is influenced
The molding effect of seat.
