Vehicle seat

A vehicle comprising:

• a vehicle body;
• a seat mounted in an interior region of the vehicle body, the seat comprising:
• a seatback configured to support an occupant's upper body, the seatback comprising:
• a lower seatback part;
• an upper seatback part comprising a tilting part pivotably hinged onto the lower seatback part so as to be tiltable forward and backward with respect to the lower seatback part as the upper seatback part is pivoted forward and backward about the lower seatback part;
• a lower frame part having a lower end hinge-coupled to a base bracket so as to be pivotable forward and backward to recline the seatback;
• and
• an upper frame part having a lower end hinge-coupled to an upper end of the lower frame part so as to be pivotable forward and backward, the upper frame part being a part of the tilting part;
• and
• a tilting device configured to tilt the tilting part forward and backward in conjunction with a reclining operation of the seatback, wherein the tilting device is configured to tilt the tilting part forward in conjunction with a backward reclining operation of the seatback, and wherein the tilting device comprises:
• a reclining interworking drive mechanism configured to provide an actuating force for forward tilting of the tilting part in conjunction with the backward reclining operation of the seatback;
• a cable configured to transfer the actuating force provided by the reclining interworking drive mechanism;
• and
• a pivot mechanism mounted between the upper frame part and the lower frame part to pivot the upper frame part forward with the actuating force transferred through the cable so that the tilting part is tilted forward.

A seat comprising:

• a base bracket;
• a seatback comprising:
• a lower seatback part comprising a lower frame part having a lower-frame-part lower end hinge-coupled to the base bracket, such that the lower seatback part is configured to pivot and tilt forward and backward relative to the base bracket,
• an upper seatback part comprising an upper frame part having an upper-frame-part lower end hinge-coupled to a lower-frame-part upper end of the lower frame part, such that the upper seatback part is configured to pivot and tilt forward and backward relative to the lower seatback part;
• and
• a tilting device configured to tilt the upper seatback part forward in conjunction with a backward tilting of the lower seatback part, wherein the tilting device comprises:
• a tilting interworking drive mechanism configured to provide an actuating force for forward tilting of the upper frame part in conjunction with backward tilting of the lower frame part,
• a cable configured to transfer the actuating force provided by the tilting interworking drive mechanism, and
• a pivot mechanism mounted between the upper frame part and the lower frame part configured to pivot the upper frame part forward with the actuating force transferred through the cable so that the upper seatback part is tilted forward.
