Description

Knobless Armrest Assembly {KNOBLESS ARMREST ASSEMBLY}

Embodiments of the present invention relate to an armrest assembly for a vehicle.

The vehicle includes an armrest for the convenience of the driver and other passengers. Armrests are provided in various forms inside vehicles (indoors). For example, the armrest may be provided in a form that forms a vehicle seat, a form that forms a center console disposed between the driver's seat and the passenger seat in the vehicle, etc.

In general, an armrest for a vehicle is configured so that the armrest body can rotate around an axis, a knob is provided at the tip of the armrest body, and the rotation of the armrest body is restricted or linked to the operation of the knob. and a locking device configured to allow.

Such vehicle armrests have problems in that the structure of the locking device is very complicated and/or that the operating relationship of the locking device becomes inaccurate during long-term use. Accordingly, high costs are inevitably required for manufacturing and/or maintenance.

In addition, in order to rotate the armrest body, the locking device must be released from the armrest body by manipulating the knob, and for this, the passenger must place his or her hand close to the knob. Therefore, the armrest body can only be rotated through consistent manipulation. There are some inconveniences in use.

Additionally, if the armrest forms a center console between the driver's seat and the passenger seat, the armrest body may act as an element that restricts or hinders the actions of the occupants in the driver's seat or passenger seat.

Meanwhile, one of the requirements for future vehicles is more diverse seat variations, and the related industry is trying to more efficiently implement forward and backward movement, left and right movement, and/or swiveling of the seat for seat variation. We are actively conducting research and development for this purpose. In this situation, the current armrest that constitutes the center console can greatly impede seat variation.
