An automobile seat and an automobile comprising same, the automobile seat comprising a seat base, a seat back and a seat back adjusting mechanism; the seat back adjusting mechanism comprises a rotating part which is disposed at the lower end of the seat back; the rotating part rotates about the rear end part of the seat base to enable the angle between the seat back and the seat to be changed, and the center of rotation of the rotating part is located below the upper end surface of the seat base. A small step difference may be formed between the lower end part of the seat back and the upper end surface of the seat base when the seat back rotates, and a step difference may even be avoided. The lower end part of the seat back basically does not abut against and press the back of a passenger.

Automobile seat and automobile comprising same

A vehicle seat with an energy absorption structure, includes a cushion side plate and an angle adjuster lower connection plate, wherein an impact groove is provided on the angle adjuster lower connection plate, and the impact groove includes a straight groove part and a circular groove part communicating each other from top to bottom. The vehicle seat further includes an energy absorption disc including an annular part, a position part and impact fracture parts connected between the annular part and the position part. A first nut is securely coupled to the cushion side plate. A step bolt is provided including a head part, a step part and a stud which are coaxially connected in sequence. The stud bolt passes through the circular groove part, the annular part and threads to the first nut to make the step part passing through the circular groove part and press-fitting with the energy absorption disc. The vehicle seat has a simple structure, convenient installation, and can absorb energy during collision so as to reduce the head rebound speed during the vehicle collision and protect passengers, thereby improving vehicle safety level.
