Seat with an integral seatbelt

A seat with an integral seatbelt, comprising:

• a seat back frame including:
• vertical longitudinal frames disposed in a left position and a right position to each other and linked respectively at lower parts thereof to a seat cushion frame end, and
• a transverse frame linking the vertical longitudinal frames to each other;
• a seatbelt retractor attached to a lower part of one of said vertical longitudinal frames and configured to provide an emergency locking;
• a seatbelt linked at one end thereof retractably to the seatbelt retractor, attached at another end thereof to the seat cushion frame end, and provided with an engagement member between the seatbelt retractor end and the seat cushion frame end;
• a locking member fixed to one of the vertical longitudinal frames and the seat cushion frame end and configured to disengageably lock the engagement member;
• and
• an upper part supporter provided at an upper part of the vertical longitudinal frame having the seatbelt retractor attached to the lower part thereof, and configured to support the seatbelt at a return point to the upper part supporter, wherein
• the vertical longitudinal frame having the seatbelt retractor attached to the lower part thereof has a hollow formed within a closed section, and the seatbelt retractor is mounted inside the hollow of the closed section, and the seatbelt penetrates the hollow of the closed section from the seatbelt retractor to the upper part supporter, and wherein
• the seatbelt retractor and the upper part supporter are arranged to transmit a load acting from the seatbelt on the upper part supporter, in a compression direction of the vertical longitudinal frame having the seatbelt retractor attached to the lower part thereof.
