Lyric Product Advantages

Gravity Tip-Up Seat The Lyric seat tip-up action is attained by the use of a gravity counterweight. The advantages of a gravity mechanism over a spring or cylinder mechanism are as follows:

Consistent and automatic return to the upright position. Spring mechanisms can have inconsistent tip-up action due to the variation of the strength or fatigue of the steel springs. This affects the aesthetics of the room and may affect compliance with egress codes since the seats may not return to a consistent upright position.

Silent action. Spring mechanisms are likely to develop squeaks and normally produce several loud hits before coming to a stop.

Seat tip-up will never fail. Because the Lyric mechanism relies on gravity, it will never fail to return the seat to its upright position. In contrast, as a spring mechanism fatigues, the seat tip-up action will get slower. Eventually, the spring mechanism may fail to return the seat to the upright position, producing a possible violation of egress codes.

Seat Construction The Lyric seat is a combination of a rugged steel frame which is built for tough commercial use and a comfort system that is designed to provide a supportive yet soft feel resulting from the use of elastic suspension webbing. This system provides a flexible platform for the polyurethane seat cushion which ensures comfort during extended seating periods and durability over the lifetime of the product.

Silence, durability, comfort. Lyric’s flexible polyurethane foam and elastic web construction offers significant user comfort over long seating periods. Seats constructed with serpentine springs often fatigue, sag and fail. This creates an uncomfortable and noisy seat, which may require replacement. Additionally, the absence of steel springs ensures completely silent compression during use.

Lyric Chair Frames The Lyric frames are welded assemblies of heavy gauge and solid steel components. The advantages of this type of construction are listed below:

Flexibility. The Lyric’s welded steel assembly allows for simple and cost-efficient design modifications for conformance to unique building conditions. Unlike high volume castings, welded construction facilitates small production run modifications.

Seat Hinges The innovative Lyric seat hinge is molded of Dupont Zytel material and is designed for silent operation

Lyric Installation Instructions

 

1. Use approved floor plan to establish hole locations for the foot plates. Note that the chair radius line coincides with the front hole of the foot plate. Accurate center-to-center width spacing is critical to a proper installation. Tolerance on the chair width dimension is plus or minus 1/8". It is critical not to exceed this tolerance on width spacing.

2. When mounting chairs over carpet, punch two 5/8" diameter holes in carpet to match holes in the chair base plate. Bolt leg frames to floor as per the appropriate anchoring method. Use 1/4" machine nut or wood screws and lock washers. Hand-tighten to allow for some slight movement in the leg frame.

3. Attach back as follows: From the back, slip bottom two attachment bolt heads into round end slots in leg frame bracket. Adjust bolt heads to insure snug fit to inside of leg frame bracket. Rotate top of back forward so that the top two attachment brackets align with threaded holes at the top of leg frames. Install 1/4-20 x 5/8” SEMS machine screws through round end slots in brackets of adjacent backs. Use one bracket only on end leg.

4. Orient the seat in the tip-up position and rotate the rectangular heads of the mounting bolts protruding out of each side of the seat until the heads are oriented vertically and are in alignment with the “T” notch in the top of the hinge. Insure that the bolts are extended equally on each side. Lower the hinge bolts into the T-slots. Insure that seat is centered between legs prior to final tightening; adjustment can be made by rotating the mounting bolts in or out of the side mounting plate in order to align with the at rest position of the hinge T-slots. Insert the seat pin through the bottom hole in the hinge and into the matching hole in the seat side bracket. Tighten seat pin on both hinges and check to be sure that the seat tips up without binding.

5. Flip seat up and down several times to insure that it pivots and returns to upright position freely. Adjustments can be made to the attachment bolts in either the seats or the backs.

6. Attach curved armrest by aligning the three pilot holes in the underside of the armrest with the matching holes in the top plate of the leg. Install (3) #8 sheet metal screws. Attach flat wood armrest by using one 10-24 x 1” machine screw at the front and one 10-24 x 2-1/2” machine screw at the rear.

7. Tighten all floor attachments securely and install bolt covers onto foot plate.

 

Maintenance Instructions

The Lyric chairs are designed and built for years of reliable service. The durability and beauty of the chair will however, be greatly enhanced with proper care and inspection, as described below. Each project will be provided with an Operations and Maintenance (O&M) Manual which will describe in detail the maintenance measures to be taken by onsite personnel. For more information on the care of the veneer and fabric components of your product, please refer to the Finishes section of the Theatre Solutions binder.

Preventative Maintenance

Inspection and Cleaning

During the first year after the original installation, it is recommended that the chairs be inspected quarterly to insure that all chairs remain secure to the floor, and that the seats and backs remain tight to the leg frames. After the first year, this inspection interval can become longer, but should never exceed 6 months.

Lubrication

There are no components in the Lyric chair which require lubrication. Seat pivot hinges are manufactured of nylon and insure silent and consistent performance.

Periodic Readjustment

Besides inspecting for loose screw attachments, there is no routine need for readjustment. If, however, a loose connection is discovered, please refer to the appropriate drawing and instructions for installing the subject component. These drawings and instructions can be found in the O&M Manual.

Corrective Maintenance

The Lyric chair has been designed and tested to achieve optimum performance and durability. In general, onsite maintenance personnel can provide the appropriate service to correct problems if they have the necessary spare parts and installation instructions.

Troubleshooting

In the event that a problem with the performance or finish of the chair occurs, it is often possible for immediate on-site remedies. TSI recommends that any loose component should be inspected for any visible evidence of breakage. If evidence is found, the part should be immediately replaced. If there is no evidence of breakage, the attachment hardware should be checked to insure tightness.

Obtaining Replacement Parts

A complete list of spare parts provided with the original installation is included in the O&M Manual. If any additional parts are required, simply contact Theatre Solutions and refer to the appropriate part number or the description listed in a drawing depicting the component.
