Description

Pedal transmission structure of connecting rod type automobile seat Technical Field The utility model relates to the technical field of automobile seats, in particular to a pedal transmission structure of a connecting rod type automobile seat. Background With the rapid development of the automobile industry, the comfort of riding for rear passengers is increasingly promoted, and therefore, providing pedal support for rear passengers becomes an important direction for optimizing riding experience. In the prior art, the rear pedals of an automobile are usually rotatably arranged on the back side of a front seat backrest, the pedals can be folded on the back side of the front seat backrest when not in use, and the pedals can be outwards rotated and unfolded when in use. However, the pedals installed in this way currently present some significant drawbacks. On the one hand, the parts for controlling the pedal to rotate are complex and occupy space. Another convenience is that the gooseneck in the attachment structure will be exposed when the foot pedal is deployed. The exposed gooseneck rod not only affects the overall aesthetic degree in the vehicle, but also occupies limited space in the vehicle to a certain extent, and causes interference to the leg movement range of the rear-row passengers. Disclosure of utility model In view of the above, the utility model provides a pedal transmission structure of a connecting rod type automobile seat, which has the advantages of simple and compact structure.
