Passenger seat with armrests

Claim 1

A passenger seat comprising seating and backrest sections, armrest support means associated with said seating and backrest sections, and an armrest pivotally supported on said armrest support means about a pivot axis, said armrest and armrest support means having circular grooves formed therein radially spaced from, and concentric with, the pivot axis of said armrest and disposed opposite one another and shaped so as to form together an annular cavity with wedge-shaped axial ends, a bearing ring comprising an elastomeric material disposed in said annular cavity between said armrest support means and said armrest, said bearing ring having conical side sections corresponding to a wedge-shaped annular cavity, and a bolt extending through an opening in one, and threaded into the other, of said armrest and said armrest support means for axially compressing said armrest and armrest support means into firm engagement with the elastomeric bearing ring therebetween, the opening in said one of said armrest and armrest support means being substantially larger in diameter than said bolt so as to provide, between said bolt and the walls defining said opening, a clearance which is sufficient to prevent contact between said walls and said bolt, thereby to prevent rattling of said armrest.
