Seat

Abstract

A seat includes a seating portion, a backrest, two pairs of vibrators and a vibration absorbing member, and constitutes a driver’s seat of a vehicle. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the seating portion, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the backrest, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region.

1 . A seat having a first region and another region, comprising:
 a first vibrator arranged in the first region; and   a propagation suppressor that suppresses vibration of the first vibrator from being propagated to the another region,   wherein the propagation suppressor is a vibration absorbing member that is arranged inside the seat at a central portion in a width direction of the seat,   wherein the vibration absorbing member extends from a front to a rear of a seating portion of the seat or from a bottom to a top of a back portion of the seat, and   wherein the vibration absorbing member is constituted of a member that is separate from a cushioning member inside the seating portion or the back portion of the seat.   
     
     
         2 . The seat as claimed in  claim 1 , further comprising:
 a second vibrator arranged in the another region,   wherein the propagation suppressor is configured to suppress vibration of the second vibrator from being propagated to the first region.   
     
     
         3 . The seat as claimed in  claim 1 , wherein the propagation suppressor is constituted of a material in which vibration is not likely to be propagated to the cushioning member inside the seating portion or the back portion. 
     
     
         4 . A seat having a first region and another region, comprising:
 a first vibrator arranged in the first region; and   a propagation suppressor that suppresses vibration of the first vibrator from being propagated to the another region,   wherein the propagation suppressor is a dividing groove configured to divide an inner member of the seat into right and left portions at a central portion in a width direction of the seat.   
     
     
         5 . The seat as claimed in  claim 4 , further comprising:
 a second vibrator arranged in the another region,   wherein the propagation suppressor is configured to suppress vibration of the second vibrator from being propagated to the first region.   
     
     
         6 . The seat as claimed in  claim 2 , wherein the propagation suppressor is constituted of a material in which vibration is not likely to be propagated to the cushioning member inside the seating portion or the back portion.
