Angle-adjusting apparatus for a housing of headrest display

Abstract

An angle-adjusting apparatus for a housing of a headrest display, comprising an external housing having an opening at the outer side thereof, a cavity being formed and two sleeves being symmetrically arranged at both sides thereof, a spring element being provided at a top and a bottom side of the cavities, the spring element having a first projecting rib longitudinally extending at an internal side thereof; an internal housing having a front and a rear portion with an internal room for installing a display, a groove and two positioning sleeves corresponding to the cavities of the external housing being disposed at both sides of the internal housing, the internal housing further having a plurality of second projecting ribs at a position corresponding to the spring element; and a left link element and a right link element formed in a symmetric manner and received within the cavities of the external housing, respectively. Each of the left and right link elements includes an external and internal link portion both of which are locked on the external and internal housings, respectively, for a pivotal connection. And the joining end is limited to the lowest point so that a room is reserved to install the display in the small headrest. Moreover, the contact at both sides includes a plurality of engaging and positioning points to allow for a precise angle-adjustment and to protect from loosening due to the rocking action when driving. Accordingly, an optimal view angle can be achieved.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an angle-adjusting apparatus for a housing of a headrest display, and more particularly to a housing that is adapted to the headrest in an automobile to allow for a fine adjustment of the view angle. [0003] 2. Description of the Related Art [0004] For the recent years, miniaturization features the developments of the display. The LCD displays have been widely installed in the automobiles. If the display is mounted at the front side of the automobile, it usually mounted on the top of the front panel of the car or embedded therein. The display is pulled out when used. If the display is installed in the area of the rear seat, it will be usually installed at the center handrail of the front seat or under the roof, and the display can be pulled out of the roof when used. [0005] If the display is installed under the roof for the rear seat passengers, the rearview mirror can't provide the driver wi...
