| 发明名称 | Seat cushion extension apparatus | ||
| 摘要 | A seat cushion extension apparatus includes an extension motor supported on a cushion frame, an extension mounting bracket holding an extension cushion such that the extension cushion is displaceable forward and backward on a seat cushion, and a power transmission unit connecting between the extension motor and the extension mounting bracket. The power transmission unit receives power from the extension motor and moves the extension mounting bracket forward and backward. A slide device is coupled with the extension mounting bracket, and supports the extension mounting bracket such that the extension mounting bracket is slidable forward and backward in the cushion frame. The front-back length of the seat cushion can be freely extended, and limitations in the thickness of a cushion pad or the like are removed. | ||

| 主权项 | 1. A seat cushion extension apparatus, comprising: an extension motor supported on a cushion frame; an extension mounting bracket holding an extension cushion such that the extension cushion is displaceable forward and backward on a seat cushion; a power transmission unit connecting between the extension motor and the extension mounting bracket, wherein the power transmission unit receives power from the extension motor and moves the extension mounting bracket forward and backward; and a slide device coupled with the extension mounting bracket, wherein the slide device supports the extension mounting bracket such that the extension mounting bracket is slidable forward and backward in the cushion frame, wherein the power transmission unit comprises: a lead screw coupled with the extension mounting bracket, wherein the lead screw moves forward and backward to displace the extension mounting bracket; anda gear unit which converts a rotational force of the extension motor into a force that moves the lead screw forward and backward, wherein a driving shaft of the extension motor is coupled with and supported by the gear unit, wherein a hinge bracket is disposed on the gear unit, and is hinge-coupled with a motor mounting bracket fixed to the cushion frame, and wherein a front end of the lead screw is coupled with the gear unit, and is hinge-coupled with the extension mounting bracket. | ||
