Patent attributes
An armrest device includes an armrest mount, an armrest member coupled to and rotatable relative to the armrest mount about a pivot axis, a latch member that extends through the armrest member and into the armrest mount and that is movable in a direction parallel to the pivot axis between locking and unlocking positions, and an armrest button mounted movably on the armrest member and operable to move along a button axis transverse to the pivot axis for driving movement of the latch member from the locking position to the unlocking position. The latch member engages the armrest mount to arrest rotation of the armrest member relative to the armrest mount when in the locking position, and is disengaged from the armrest mount to permit rotation of the armrest member relative to the armrest mount when in the unlocking position.
