1. A seat lifting device comprising:
- a linking mechanism arranged and constructed to movably interconnect a seat support for supporting a seat cushion and a seat mount for mounting the seat support, so that the seat cushion is vertically adjusted when the linking mechanism is operated;
a seat support pulling means arranged and constructed to be connected to the seat support and the seat mount, the seat support pulling means being adapted to be shortened when the seat support is subjected to an impact, and an actuator for actuating the seat support pulling means, wherein the actuator is adapted to shorten the seat support pulling means when the seat support is subjected to the impact thereby forcing the seat support toward the seat mount, and wherein the actuator comprises a drive means of a seatbelt pretensioning device.

7. A vehicle seat, comprising:
-
a seat body comprising a seat cushion and a seat back;
a seat support for supporting the seat cushion;
a seat mount for mounting the seat support to a vehicle body;
a linking mechanism that is disposed between the seat support and the seat mount and is adapted to vertically adjust the seat support relative to the seat mount;
a seatbelt for restraining an occupant of the scat body to the seat body when a vehicle is subjected to an impact;
a seatbelt pretensioning device attached to the seal support, the seatbelt pretensioning device being adapted to pull a first wire connected to one end of the seatbelt when the vehicle is subjected to the impact; and
a connecting member having a first end that is incorporated into the seatbelt pretensioning device and a second end that is connected to the seat mount, the connecting member having a length required to move the seat support relative to the seat mount and being arranged and constructed to be pulled into the seatbelt pretenisioning device together with the first wire. - View Dependent Claims (8, 9)

10. A vehicle seat, comprising:
-
a linking mechanism movably interconnecting a seat support and a seat mount;
a seatbelt for restraining an occupant when a vehicle is subjected to an impact, the seatbelt being connected to the seat support at a connecting position;
a seat support pulling means connected to the seat support and the seat mount, wherein the seat support pulling means has a substantial length so as not to interfere with upward and downward motion of the seat support relative to the seat mount when the linking mechanism is operated, wherein the seat support pulling means has a first end that is connected to the seat support and a second end that is connected to the seat mount, and wherein the first end is positioned adjacent to the seatbelt connecting position and the second end is positioned rearwardly relative to the first end; and
an actuator for actuating the scat support pulling means so as to shorten the seat support pulling means when the vehicle is subjected to the impact.
