Ottoman Device

Abstract

The present invention provides an ottoman device with a structure in which a link device including a leg support and a link frame to which the leg support is attached and an electric driving device for driving the link device are modulated on a fixing frame as a base connected to a vehicle body beneath a rear seat. As a result, the ottoman device of the present invention can be simply attached to and detached from the vehicle body, can be applied to a vehicle having no center console on the rear seat, and can increase strength with a both-side supporting structure of the leg support, differently from a conventional one arm type leg support.

1 . An ottoman device comprising:
 a fixing frame positioned beneath a seat;   a leg support folded to and unfolded from a bottom of the seat with respect to the fixing frame with an adjustable angle;   an electric driving device mounted on the fixing frame and providing a rotational force; and   a link device including a link frame, to which the leg support is integrally attached onto, and a plurality of links pivotally coupling the line frame and the fixing frame,   wherein at least one of the plurality of links is coupled to the electric driving device and rotated by the rotational force of the electric driving device to operate the link frame and the leg support.   
   
   
       2 . The ottoman device of  claim 1 , wherein the electric driving device comprises:
 a drive motor fixedly mounted on the fixing frame;   a gear box assembled to the drive motor and transmitting a rotational force of the drive motor;   a drive shaft provided co-axially on both lateral sides of an output portion of the gear box and rotated by receiving the rotational force of the drive motor through the gear box; and   a gear device provided at both ends of the drive shaft and operating the link frame and the at least one of the plurality of links as the drive shaft rotates.   
   
   
       3 . The ottoman device of  claim 2 , wherein the gear device comprises:
 a drive gear integrally assembled to both ends of the drive shaft; and   a driven gear engaged with the drive gear and connected the at least one of the plurality of links to operate the link device by the rotation of the drive gear.   
   
   
       4 . The ottoman device of  claim 3 , wherein the drive gear and the driven gear are rotatably supported by a gear bracket mounted on a front surface of the fixing frame. 
   
   
       5 . The ottoman device of  claim 3 , wherein one end of the at least one of the plurality of links is coupled to the gear device and the other end thereof is coupled to a lower side of the link frame, and
 wherein the other ones of the plurality of links couple the fixing frame and upper side of the link frame.   
   
   
       6 . The ottoman device of  claim 2 , wherein the link device further comprises:
 a first link coupling the gear devices formed at both ends of the drive shaft and the link frame; and   a second link coupling the link frame and the fixing frame,   wherein the first link is rotated by the gear device to operate the link frame and, at the same time, the second link on the fixing frame holds both sides of the link frame and rotates.   
   
   
       7 . The ottoman device of  claim 6 , wherein the gear device comprises:
 a drive gear integrally assembled to both ends of the drive shaft; and   a driven gear engaged with the drive gear and connected to the first link to operate the link device by the rotation of the drive gear.   
   
   
       8 . The ottoman device of  claim 7 , wherein the drive gear and the driven gear are rotatably supported by a gear bracket mounted on a front surface of the fixing frame. 
   
   
       9 . The ottoman device of  claim 6 , wherein one end of the first link is coupled to the gear device and the other end thereof is coupled to a lower side of the link frame, and
 wherein one end of the second link is coupled to the fixing frame and the other end thereof is coupled to an upper side of the link frame.
