Adjustable chair for vehicles

Abstract

A chair adjustment mechanism suitable for use in vehicles including aircraft. The mechanism allows the chair to be easily moved in a horizontal place and locked into any position within a boundary of this plane. This movement includes swivel movement in 360 degrees.

What is claimed is:  
     
         1 . An adjustable chair comprising: 
 a base assembly;    a seat assembly moveably coupled to the base assembly;    a locking assembly coupled to the seat assembly;    a spindle assembly coupled to the locking assembly including an adjustment device to control a clamped dimension;    a disk assembly coupled to the spindle assembly and secured by the adjustment device; and    an actuator mechanism coupled to the housing to activate the locking assembly.    
     
     
         2 . The adjustable chair of  claim 1  wherein the locking assembly comprises: 
 a guide to allow a range of movement relative to the spindle assembly.  
 
     
     
         3 . The adjustable chair of  claim 2  wherein the locking assembly further comprises: 
 at least one spring coupled to the spindle assembly to bias the spindle assembly into a locked position.  
 
     
     
         4 . The adjustable chair of  claim 2  wherein the actuator mechanism comprises: 
 a cam coupled to the locking assembly to engage or disengage the locking assembly.  
 
     
     
         5 . The adjustable chair of  claim 1  wherein the locking assembly is configured to move the spindle assembly from a first position to a second position.  
     
     
         6 . The adjustable chair of  claim 3  wherein the locking assembly further comprises: 
 at least one glide block coupled to the cam and to the spindle assembly to engage or disengage the locking assembly.  
 
     
     
         7 . The adjustable chair of  claim 4  wherein the actuator mechanism further comprises: 
 a cable coupled to a handle.  
 
     
     
         8 . The adjustable chair of  claim 4  wherein the actuator mechanism further comprises: 
 an electronic device to actuate the locking assembly.  
 
     
     
         9 . The adjustable chair of  claim 1  wherein the spindle assembly further comprises: 
 a spring to move the spindle assembly to an unlocked position.  
 
     
     
         10 . The adjustable chair of  claim 2  wherein the adjustment device comprises: 
 at least one screw to maintain the position of the adjustment device relative to the spindle assembly and the disk assembly.  
 
     
     
         11 . A mechanism comprising; 
 a housing;    a lock mechanism coupled to the housing, including an adjustment device to secure a clamped dimension;    a disk assembly coupled to the lock mechanism to apply a force to a surface.    
     
     
         12 . The mechanism of  claim 11  wherein the lock mechanism comprises: 
 a guide to allow a range of movement relative to a spindle assembly coupled to the disk assembly.  
 
     
     
         13 . The mechanism of  claim 12  wherein the lock mechanism further comprises: 
 at least one spring coupled to the housing to move the spindle assembly to a locked position.  
 
     
     
         14 . The mechanism of  claim 11  further comprising: 
 an actuator mechanism including a cam coupled to the lock mechanism and the housing to engage or disengage the lock mechanism.  
 
     
     
         15 . The mechanism of  claim 11  wherein the lock mechanism is configured to move a spindle assembly from a first position to a second position.  
     
     
         16 . The mechanism of  claim 13  wherein the lock mechanism further comprises: 
 at least one guide block coupled to the cam and to the spindle assembly to engage or disengage the locking mechanism.  
 
     
     
         17 . The mechanism of  claim 14  wherein the actuator mechanism further comprises: 
 a cable coupled to a handle.  
 
     
     
         18 . The mechanism of  claim 14  wherein the actuator mechanism further comprises: 
 an electronic device to actuate the lock mechanism.  
 
     
     
         19 . The mechanism of  claim 11  further comprising: 
 a spindle assembly including a spring to move the spindle assembly to an unlocked position.  
 
     
     
         20 . The mechanism of  claim 11  wherein the adjustment device comprises: 
 a dowel to maintain the position of the adjustment device in a guide.  
 
     
     
         21 . An adjustment control mechanism comprising: 
 a housing;    a disk coupled to the housing;    a means for locking an object between the brake disk and housing; and    a means for adjusting a clamped dimension.
