In a vehicle seat, when the occupant is seated on the seat, the seat is often uncomfortable according to the size of the body, and especially when the passenger boards the vehicle for a long time, the legs feel swollen or uncomfortable. Therefore, some vehicles are provided with a seat extension 100 that supports the legs so that the occupant can be seated on the seat more comfortably and comfortably.

The seat extension 100 is a device that operates to support the passenger's leg by moving the module unit 120 so that forward and backward movements are made on the inner side of the panel unit 110 at the bottom of the seat according to the passenger's convenience.

The seat extension 100 includes a panel unit 110 positioned at the lower end of the seat, and a module unit 120 positioned on the inner side of the panel unit 110 to be in direct contact with the legs by linearly moving forward. The module unit 120 is divided into two first modules 122 and a second module 123 to provide the most optimized comfort for both legs, each

module

122, 123 is a first lever ( The operation is performed independently by the 131 and the second lever 132.

On the other hand, the driving unit 140 for smooth operation of the module unit 120 is seated on the block unit 150 located between the panel unit 110 and the module unit 120. The block unit 150 is positioned at the lower end of the panel unit 110, and an internal space is formed in the body of the block unit 150 so that the driving unit 140 may be seated and operated.

The driving unit 140 mounted in the inner space of the block unit 150 may further include a plate 152 that allows the driving unit 140 to operate in a limited range without departing from the block unit 150 during operation. . A hole is formed in one surface of the plate 152 to allow the driving shaft 142 to penetrate forward and backward in the longitudinal direction.

The driving unit 140 is disposed on the lower surface of the module unit 120, and includes a bracket 141 for rotatably supporting the driving shaft 142 and a lever 130 for rotating the driving shaft 142.

The lever 130 is connected to the end of the bracket 141 by the pin 136 to rotate up and down, and the first gear 134 located inside the lever 130 is formed at the end of the drive shaft 140. The teeth of the lever 130 are coupled to the second gear 144 to be transmitted in the rotational direction of the drive shaft 142.

The first lever 131 and the second lever 132 operate the first module 122 and the second module 123, respectively, and may adjust the module unit 120 to a desired length according to the user's convenience. .

In addition, the first lever 131 and the second lever 132 is further provided with a locking device 133 to be operated at the same time even if one lever 130 is operated, the first module 122 and the second module 123 ) Works simultaneously.

3 is a perspective view showing a lower surface of the driving unit.

The first module 122 and the second module 123 operated by the first lever 131 and the second lever 132 are all operated by the driving unit 140 having the same shape. Accordingly, an internal configuration will be described by using one driver 140 as an example.

The driving unit 140 is rotatably connected to the lever 130 and the drive shaft 142 to the bracket 141 consisting of the wing 141a and the support 141b.

On the front face of the bracket 141, a pair of wings 141a are formed. The lever 130 is rotatably connected to the blade 141a by the pin 136, the first gear 134 is integrally formed inside the lever 130, and the pin 136 is firstly formed. It is connected to the bracket 141 through the center of the gear 134.

The drive shaft 142 is rotatably provided on the support 141b of the bracket 141, and a second gear 144 is positioned at one end of the drive shaft 142 and connected to the elastic body 146 at the other end thereof, respectively. The gear 134 and the second gear 144 are toothed.

The elastic body 146 connected to the driving shaft 142 is fixed to the bracket 141, and the guide shaft 148 is inserted into the elastic body 146 to be in contact with the driving shaft 142.

Therefore, when the lever 130 is operated, the first gear 134 is rotated, and the second gear 144 rotates the drive shaft 142 to increase and decrease the length of the elastic body 146.

4 to 6 show the operation of the sheet extension according to each process.

In order to support the leg by advancing the module unit 120 positioned on the same line as the seat, first, hold the lever 130 located at the front end of the module unit 120 by hand and slightly lift it up.

When the lever 130 is raised, the lever 130 fixed to the pin 136 rotates, and the second gear 144 coupled with the first gear 134 provided in the lever 130 is driven on the drive shaft. Rotate counterclockwise with 142.

As the driving shaft 142 is rotated, the elastic body 146 elastically supporting the driving shaft 142 and the support 141b is elongated, and the fixing force for fixing the guide shaft 148 is released to thereby couple the driving unit coupled to the panel unit 110 ( 140) advances.

At this time, a plate 152 suggesting a moving distance is connected to the driving shaft 142 so that the driving unit 140 mounted on the block unit 150 can operate within a predetermined range, and the module unit 120 is the panel unit 110. Departure from is prevented. The driving unit 140 and the module unit 120 are coupled to each other so that they operate together.

On the contrary, if you want to return to the original position or to reverse the module unit 120 to the original position, pressing the lever 130 down and proceeds in the reverse order of the previous procedure to the first gear 134 of the lever 130 The module unit 120 reverses by rotating the drive shaft 142 in the opposite direction.

7 shows an operation of the seat extension according to the present invention.

When the occupant lifts the lever 130 upward, the module unit 120 provided on the seat moves forward to support the leg of the occupant, and to support the leg at a higher position according to the convenience of the occupant, the lever 130 ), The module unit 120 can be moved further forward.

Both the first module 122 and the second module 123 operate in the same manner as described above, and when the locking device 133 provided in the first lever 131 and the second lever 132 is fastened, The first lever 131 and the second lever 132 operate together to move the first module 122 and the second module 123 simultaneously.

That is, the module unit 120 may be operated simultaneously or separately through the locking device 133 provided in the lever 130.

In addition to the manual method of connecting the drive shaft 142 and the lever 130, the drive shaft 142 may be used in a fully automatic manner that can be operated by a switch by connecting the electric motor.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
