  • Latching device for a head restraint
    Patent number: 9004602
    Abstract: In a latching device for a head restraint, a locking element is movably mounted in a carrier device. The locking element can be moved from a locked position into an unlocked position by actuation of an actuating device. The latching device is movably mounted with respect to a retaining rod. In the unlocked position, the locking element allows the latching device to be moved with respect to the retaining rod, while in the locked position the locking element engages in at least one cut-out of the retaining rod for latching the latching device with respect to the retaining rod. According to the invention, in the locked position the carrier device, together with the locking element arranged therein, is mirror-symmetrical to an xz plane extending substantially perpendicularly to the carrier device.
