  • Patent number: 4114948
    Abstract: An auxiliary headrest for an automobile has a U-shaped cushion body of relatively soft foam material including a back cushion portion and spaced side cushion portions extending forwardly of the back cushion portion to define a space receiving the back of a user's head; a rearwardly extending support member is spaced from the medial horizontal plane of the cushion body and is positioned between the built-in headrest and the top of the back of an automobile seat for maintaining the auxiliary headrest forwardly of the built-in headrest. The height of the U-shaped cushion can be varied by inverting the headrest.

  • Patent number: 4113311
    Abstract: A single pivot connection for a legrest of a vehicle seat and the like includes a shaft extending from a bracket attached to the seat and an arm bracket attached to the legrest and pivotally supported upon the shaft. The arm bracket has a cylindrical portion and there is a hub on the end of the cylindrical portion with a circumferentially extending notch therein which receives a key formed in an annular member rotatably positioned upon the hub. A gear mounted on the shaft is engageable with a pawl and there is a braking disc between the end of the cylindrical portion and gear such that the application of a predetermined force on the legrest will pivot the legrest with respect to the seat. The pawl engages the gear as the legrest pivots to a horizontal position and pivoting beyond the horizontal to the vertical up position causes cam surfaces on the annular member to disengage the pawl from the gear so that the legrest is free for pivotal movement.

  • Patent number: 4113058
    Abstract: A portable seat for hunters consisting of a vertical body to be placed on a tree trunk and held at the desired height by a chain having one end attached to one side of the body so that the other end may be wrapped around the tree and then removably attached to the other side of the body. A seat is hinged to the top of the body so that it can be folded into a closed position forming a flat package with all parts contained therein. When the seat is swung into open position it extends outwardly from the body into a horizontal position. A rigid non-extensible member is hinged to the underside of the seat so that it can be moved into a diagonal position with its free end engaging an abutment on the vertical body to form a strut or brace for the seat. The length of the brace and the location of the hinge are selected so that the brace is wholly within the package when the seat is moved to closed position and a spring bias is provided to keep the free end of the brace always in contact with the body.

  • Patent number: 4111483
    Abstract: A headrest mounted to the top of a dental chair backrest can readily be positioned by means of a headrest bar engaging a locking device affixed to the chair backrest. The locking device comprises a pair of resilient rubber surfaces which grip or contact the headrest bar to positively lock the headrest in position. By merely pushing the headrest to a more vertical position, the gripping or contacting of the rubber surfaces to the headrest bar is substantially eliminated to thus permit positioning of the headrest. Release of headrest will return it once again to a locked position.

  • Patent number: 4111484
    Abstract: A headrest mounted above a dental chair backrest can readily be positioned by means of a headrest bar engaging a locking device affixed to the chair backrest. The locking device comprises a pair of resilient rubber surfaces or other high friction material surfaces which grip or contact the headrest bar to positively lock the headrest in position. By merely pushing the headrest to a more vertical position, the headrest bar is caused to lose contact with the gripping surfaces. A spring-loaded block is selectively disposed through each of the high friction surfaces to urge the bar in stronger contacting relation with said high friction surfaces in any operating position of the headrest, the blocks themselves also providing low friction surfaces against which the bar may ride when the headrest is being repositioned by initially pushing it to a more vertical position.

  • Patent number: 4109959
    Abstract: A transportation seat for a vehicle and which is capable of absorbing impact energy during a crash or rapid maneuver to thereby reduce or eliminate the severity of and occurrence of injury to a passenger includes a support frame having a leg structure and fixedly secured to the floor of the vehicle. A seat frame adapted to support the seat cushions is slidably connected to the support frame. A plurality of springs positioned between the support frame and the slidable seat frame permit controlled movement of the seat in a forward direction when impacted from the rear to thereby absorb energy of the impact. Further, the head impact area of the seat back is padded and the knee impact area of the seat back is covered by a plastic back panel which encloses a closed cell foam. The upper frame is capable of absorbing energy by deaccelerating the passenger in a crash situation in a controlled manner.

  • Patent number: 4103853
    Abstract: A positive-locking cluster mount for supporting electrical transformers and like heavy objects from upright poles characterized by bearing plates held in circumferentially spaced relationship about the pole by adjustable link members and end links each having singular hook ends that engage into the slotted side walls of the bearing plates and are locked into initial loose, though positively connected, positions by the placement of the diverging support brackets thereon. This facilitates the placement of the partially assembled cluster mount at a desired position on the pole and also facilitates the final connection and tightening of the cluster mount thereabout to receive the transformers. The support brackets are assembled in outwardly diverging paired relationship from bearing plates of different lengths to accommodate small and large transformers.

  • Patent number: 4102549
    Abstract: Apparatus for adjusting a back support of a chair which includes a bracket through which the back support slides. A position stop of flexible sheet material is mounted adjacent to the back support. A stop member is included on the back support, while the position stop includes apertures therein. The stop member is engaged in one of the apertures to lock the back support in position. To move the back support, the position stop is flexed to a disengaged position in which the stop member is free from the apertures. After being moved, the position stop is allowed to return to the engaged position in which the stop member is engaged within another aperture.

  • Patent number: 4101005
    Abstract: A vertically-oriented hydraulic cylinder has its piston rod attached to a pulpit or a lectern that is vertically guided as the piston is actuated. The hydraulic cylinder contains a column of oil in the cylinder between the piston and a supply line connected to the cylinder and coming from a water main such as a city domestic supply. An exhaust line off the supply line exhausts on the piston downstroke to a drain or sump. Each of the supply line and the exhaust line is controlled by a solenoid operating valve electrically connected to a manual switch. Preferably a limit switch located to be actuated at the bottom of the downward travel of the speaker's apparatus closes the exhaust valve before the oil-water interface in the cylinder reaches the cylinder outlet to the supply line. The supply entry of the cylinder may be baffled to reduce water turbulence to preserve the interface between water and oil in the cylinder.

  • Patent number: 4099777
    Abstract: Seat positioning mechanism of the type including an elongated thin-walled housing telescopically receiving a rod with friction lock washers operable to restrain the rod against movement with respect to the housing in any selected position. The invention includes a construction for increasing the locking efficiency of the lock washers and reducing the cross-section of the housing. A slot is formed in the wall of the housing, and one end of the slot is located on the housing wall at the outer boundary of the housing to define a fulcrum. The other end of the slot forms a stop on an inwardly depressed portion of the housing wall. The lock washers have lever arms that project into the slot. The fulcrum is curved to minimize the likelihood of sideways cocking of the lock washers. Also disclosed is a novel release mechanism including a shaft rotatably supported in a mounting bracket secured to the housing.
